What is the Groman/Tjiering Collection?

The Groman/Tjiering Collection is a personal archive of postcards assembled over many decades, presented online at Postcards — The Groman/Tjiering Collection. The site's own navigation shows how the cards are grouped: bathing beauties, women, men, couples, families, Mona Lisa, architecture, and film & TV series. That mix suggests a collector's eye for both everyday social history and pop-culture imagery rather than a single narrow theme.

Who it suits

  • Designers, illustrators and collage artists hunting for period imagery and typography.
  • Historians and students interested in how people, leisure and celebrities were pictured in printed ephemera.
  • Casual browsers who enjoy vintage photography and mid-century graphic style.

What to expect

The collection is browsable by category, so the practical first step is to open one theme that matches your interest — say "architecture" or "film & TV series" — and judge the depth of that section before moving on. Because the categories are subject-based rather than dated, treat the labels as a rough guide to content, not a chronological index.

If you need images you can reuse, check the site's own terms or contact the collector before publishing anything; a personal collection page is not automatically a rights-cleared image bank.

How can I browse or search the postcards by theme like bathing beauties, couples, or Mona Lisa?

The site organizes its postcards into named theme categories, and the excerpt lists exactly the kind of groupings you mention: Bathing beauties, Women, Men, Couples, Families, Mona Lisa, Architecture, and Film & tv series. So browsing by theme means starting from those category labels rather than from a search box.

How to use it

  • Open The Groman/Tjiering Collection and look for the theme headings on the page; click a label such as Couples or Mona Lisa to see the postcards filed under it.
  • Treat the labels as the primary navigation. The collection spans many decades, so a theme like Bathing beauties or Architecture will cut across eras and give you a coherent visual set quickly.
  • If you want a specific image rather than a category, use your browser's find function on the category page (Ctrl+F or Cmd+F) to jump to a name or keyword within the visible listings.

Choosing a route

Your goal Best starting point
See a style or subject across time A broad theme like Bathing beauties or Architecture
Find a specific person or pairing Couples, Women, Men, or Families
Art-historical or novelty interest Mona Lisa
Popular-culture collecting Film & tv series

A practical next step: pick one theme, note which decades dominate it, then cross-check a second theme to see whether the same era appears — useful if you are researching a period rather than a single subject. If the collection has no visible search field, theme pages plus in-page find are your fastest route.

Are the postcard images in the collection available for purchase or licensing, and if so, how?

The site presents the Groman/Tjiering Collection as a browsable archive of postcards organized by subject — bathing beauties, women, men, couples, families, Mona Lisa, architecture, and film & TV series — rather than as a shop. Nothing in the supplied page information describes a purchase flow, a licensing program, a price list, or a rights statement, so you cannot currently buy or license an image directly through the site as described.

What that means in practice

  • Treat it as a reference and discovery resource first: useful for identifying a card, its subject category, or a visual theme across decades.
  • For any commercial or publication use, you would need to establish rights separately. Postcard copyright and reproduction rights often sit with the original publisher, photographer, or a successor company, and older cards may be in the public domain depending on date and country.
  • If you want to use a specific image, contact the collection owner directly through the site's contact details and ask about (a) availability of a high-resolution file, (b) permitted uses, and (c) any fee or credit requirement.

A useful next step

Pick the two or three cards you actually need, note the category and any visible publisher or date information on the card, and send one clear request: intended use, distribution size, duration, and whether you need exclusivity. That gives the holder enough to quote terms or redirect you to the rights owner. For general context on how postcard rights and reproductions are handled, Library of Congress and National Archives publish plain-language guidance worth reading before you negotiate.

Can I use images from the Groman/Tjiering Collection for research, publications, or commercial projects?

You can browse the collection for research, but you should not assume the images are free to publish or use commercially. The page itself is a gallery of postcards organized by subject—bathing beauties, women, men, couples, families, Mona Lisa, architecture, and film & TV series—and it does not state a license, rights holder, or permission policy. Without that, the safe default is to treat each postcard as potentially protected by copyright, and possibly by separate rights in the underlying photograph or artwork.

What that means in practice

  • Private research and study: Usually low risk. You can view, catalogue, and write about the images for your own analysis.
  • Academic publication: Often possible, but many publishers require you to clear rights or rely on a specific exception such as fair use/fair dealing. Check your publisher's rules before submitting.
  • Commercial projects: Highest risk. Advertising, merchandise, book covers, and social media promotion generally need explicit permission from the rights holder.
  • Public domain claims: Old postcards are sometimes free of copyright, but age alone is not proof. Publication date, country, and the creator's death date all matter.

A useful next step

If you want to use a specific postcard, start by identifying it precisely—publisher, date, photographer or artist, and any printed copyright line. Then contact the collection owner through the site to ask about permission and any fees. If you cannot identify the rights holder, consult your institution's copyright office or a rights-clearance specialist before publishing.

For comparison, some institutions publish clear reuse terms, while others do not:

Source type Typical reuse situation
This collection No stated license on the page; ask first
Museum open-access programs Often allow free reuse under stated conditions
Commercial stock archives Licensed for a fee

If you need images with known reuse terms, official open-access sources such as Smithsonian Open Access or Library of Congress can be worth checking alongside this collection.

How do I request high-resolution scans or permission to reproduce a specific postcard?

Contact the collection directly through the site that hosts it. The page for The Groman/Tjiering Collection presents the postcards by category (bathing beauties, women, men, couples, families, Mona Lisa, architecture, film & TV series), but it does not publish a separate licensing or reproduction form. So the practical route is to reach whoever maintains the collection and make a specific request in writing.

What to include in your request

  • Identify the card precisely: the category and any visible caption, publisher, series number, or date printed on the card.
  • Say what you need: a high-resolution scan (state your minimum pixel dimensions or print size) or permission to reproduce (state where and how — book, exhibition, website, documentary).
  • Explain the use: commercial or non-commercial, print run or audience size, and whether the image will be cropped or altered.
  • Ask about terms: whether a credit line is required, whether a fee applies, and what file format they can supply.

A realistic scenario

A local history researcher wants one architecture card for a museum panel. They note the category and any printer's mark, request a scan at 300 dpi at the intended print size, and ask whether the museum's standard credit line is acceptable. That single message gives the collection's keeper everything needed to answer yes, no, or "here are our conditions."

Decision criteria

  • If you only need to view or study the card, ask for a reference scan rather than a publication licence — it is usually simpler.
  • If you plan to publish, request written permission covering your specific medium and territory, not a general "may I use this."
  • If the card is old enough that copyright has expired in your country, you may still need the collection's cooperation for a good scan, even where permission is not legally required.

Next step

Check the site for a contact address or email, then send one concise message per card. If no contact details are visible, look for a "contact" or "about" page on tgtc.org before assuming the collection is unreachable.

What historical periods and countries are represented in the collection, and how is that reflected in the cataloging?

The cataloging reflects the collection's breadth through subject categories rather than through a dated, country-by-country index. The visible headings on Postcards — The Groman/Tjiering Collection group cards by motif: bathing beauties, women, men, couples, families, Mona Lisa, architecture, and film & TV series. That tells you the organizing principle is theme first.

What that means for historical periods and countries

  • Periods are implied rather than stated. Categories such as "bathing beauties" and "film & tv series" point to recognizable eras of popular imagery, but the page evidence does not assign dates or date ranges to individual cards, so you cannot read a chronology off the catalog structure.
  • Countries are not surfaced as a browsing facet in the excerpt. There is no visible nation, city, or publisher grouping, which is common for postcard collections where the printed image, the photographer, and the postmark can each point to different places.
  • The subject headings that do appear are culturally specific. "Mona Lisa" as its own category suggests a subset built around reproductions or parodies of a single famous artwork, while "architecture" likely spans multiple countries and decades without saying so.

How to use this as a researcher or collector

Treat the categories as an entry point, not a finding aid. If your interest is a period or a country, expect to identify it from the individual card — the image, the caption, the stamp, and the postmark — rather than from the menu. A practical next step is to open one category, such as architecture or film & TV series, and note how much item-level detail each entry carries; that will tell you quickly whether the catalog supports provenance research or is mainly a visual overview.

For comparison, institutions that do expose place and date as search facets include Library of Congress and Smithsonian Institution, where postcard and ephemera holdings are typically indexed by geography and period. If your question is specifically about which countries appear in this collection, the honest answer from the available page evidence is that the catalog does not say — you would need to browse the images themselves.

What Is the Historical Background of the Groman/Tjiering Postcard Collection?

The Groman/Tjiering Collection is a postcard archive published at tgtc.org that spans many decades, which makes it useful as a cross-era sample of popular imagery rather than a single-period set. The site itself offers only a brief description and a set of subject categories, so the collection's name, its time span, and its themes are the main historical signals available; specific provenance, dates, and collector biography are not documented on the page and would need outside verification.

What the site tells us

The page presents the collection under the heading "The Groman/Tjiering Collection" with the single subheading "postcards," and describes it as "a collection of postcards spanning many decades." That is the full extent of the historical framing provided. There is no stated founding date, no list of sources, and no narrative about how the cards were gathered.

Two things can be read from this:

  • The name — "Groman/Tjiering" appears to identify the collector, a family, or a partnership behind the collection. The site does not confirm which.
  • The span — "many decades" indicates the cards were produced across a long stretch of the 20th century and possibly beyond, giving the set value as a comparison across changing visual styles and printing conventions.

What the subject categories suggest

The collection is organized by theme rather than by date or publisher. The categories listed are:

Category What it points to
Bathing beauties Early-to-mid 20th century popular and pin-up imagery
Women Portraiture and figure studies
Men Portraiture and figure studies
Couples Romance and social scenes
Families Domestic and generational imagery
Mona Lisa Reproductions of a single famous artwork
Architecture Buildings, streetscapes, landmarks
Film & tv series Entertainment tie-ins and celebrity promotion

This mix is itself a historical clue. Postcards combining celebrity promotion, tourist architecture, and mass-reproduced fine art were a mainstream commercial format through much of the 1900s, so the category list is consistent with the "many decades" description. The Mona Lisa category in particular suggests the collection includes art reproduction cards, a common genre distinct from photographic or illustrated views.

How to use the collection as a historical source

Because the site does not date individual cards or explain their origins, treat it as a visual reference rather than a documented archive:

  1. Compare across categories to see how the same subject (for example, women or couples) was depicted in different eras.
  2. Use the categories as a starting filter when you want examples of a specific genre of popular imagery.
  3. Verify any historical claim independently — the site provides no dates, publishers, or printer marks, so attributing a card to a period requires checking the physical card or a catalogued source.

Limits to keep in mind

  • The site gives no information about who Groman and Tjiering were, when the collection was assembled, or where the cards came from.
  • No pricing, access, or licensing terms are stated on the page, so nothing can be assumed about reuse or availability.
  • "Many decades" is the only temporal statement; any more precise dating has to come from the cards themselves.

If your interest is the collection's themes and visual range, the site's category structure is enough to start browsing. If your interest is provenance or dating, the page alone will not answer it.

What kinds of postcards are included in the Groman/Tjiering Collection?

The Groman/Tjiering Collection at tgtc.org is organized around a set of subject categories rather than a single theme. Based on the site's own listing, the collection covers bathing beauties, women, men, couples, families, Mona Lisa, architecture, and film & TV series. Because the collection spans many decades, each category can contain postcards from different eras, so browsing by category is the most practical way to find what interests you.

Subject categories on the site

The page presents these categories as the entry points into the collection:

Category What it suggests you'll find
Bathing beauties Vintage seaside and swimwear imagery, a common postcard genre
Women Portraits and depictions of women across the collection's time span
Men Portraits and depictions of men
Couples Two-person romantic or companion subjects
Families Group portraits and domestic scenes
Mona Lisa Postcards referencing Leonardo's painting, likely reproductions or parodies
Architecture Buildings, landmarks, and structural subjects
Film & TV series Cards tied to screen stars, shows, and productions

Why the categories matter more than a single theme

The collection is described as spanning many decades. That has a practical consequence: a category like "Women" or "Architecture" is not a single style or period. The same heading can hold early-twentieth-century cards alongside much later ones, so the visual character, printing style, and subject treatment can vary widely within one category.

If you are looking for a particular era or aesthetic, expect to look through a category rather than assume it is uniform.

How to browse

  1. Start from the category list on the site.
  2. Pick the subject closest to your interest — people, art, buildings, or screen media.
  3. Open that category and scan the cards, keeping in mind that dates and styles will differ from item to item.
  4. Move to another category if the first doesn't match what you had in mind.

This is an informational collection site; the page evidence does not indicate pricing, accounts, or download terms, so treat it as a browsing resource for the imagery itself.

What is the Groman/Tjiering Collection website at tgtc.org?

tgtc.org is the online home of The Groman/Tjiering Collection, a personal collection of postcards spanning many decades. If you are trying to work out whether the site is a shop, an archive, or a gallery, the short answer is: it is a collection display. The site presents postcards as a curated body of material rather than as products for sale, and the categories shown on the page are the main way the collection is organised.

What the site is

The site is built around one named collection: The Groman/Tjiering Collection. Its stated scope is postcards "spanning many decades," which means the interest is historical and thematic rather than tied to a single period, publisher, or country.

The visible structure is a set of subject categories. From the page evidence, these include:

  • Bathing beauties
  • Women
  • Men
  • Couples
  • Families
  • Mona Lisa
  • Architecture
  • Film & TV series

That mix is worth noting. Some categories describe people and social types (bathing beauties, women, men, couples, families). Others describe subject matter or media (Mona Lisa, architecture, film & TV series). A collection organised this way is usually browsed by theme, not searched by date or catalogue number.

What it is not

There are no pricing signals on the page: no prices, no payment links, and no payment platforms. That is consistent with a private collection being shown publicly rather than a commercial storefront. If you arrive expecting to buy postcards, the site does not present itself that way.

It also does not read as an institutional archive with catalogue records, finding aids, or provenance documentation. The description is simply "a collection of postcards spanning many decades."

Who it is for

The site is likely to be useful if you:

  • Want to browse historical postcard imagery by theme
  • Are interested in how ordinary subjects — couples, families, bathing beauties — were depicted across decades
  • Are looking for visual reference material on architecture or film and TV imagery as it appeared on postcards
  • Enjoy personal collections presented as galleries rather than as searchable databases

It is less suited to you if you need to buy postcards, verify an item's market value, or search a formal catalogue by date, printer, or location.

How to approach it

Start from the category list and treat it as a browsing experience. Because the collection spans many decades, expect variation in style, printing quality, and subject treatment within a single category. The "Mona Lisa" and "Film & TV series" groupings in particular suggest the collection includes reproductions and popular-culture imagery alongside portrait and social-scene cards.

One practical caveat: the page evidence gives the collection name and category headings, but not the size of the collection, the identity of the collectors, or how items were acquired. If those details matter to you, they are not established by what is shown here.

How to Browse the Postcards on tgtc.org

tgtc.org is the online home of the Groman/Tjiering Collection, a set of postcards spanning many decades. The site organizes browsing around subject categories rather than a search box, so the most reliable way to explore it is to pick a category and work through it. The categories visible on the site are: Bathing beauties, Women, Men, Couples, Families, Mona Lisa, Architecture, and Film & tv series. If you already know which kind of image you want, start with the matching category; if you are just exploring, the thematic ones (Bathing beauties, Mona Lisa, Film & tv series) tend to be the most distinctive.

Start from the category list

The collection presents its postcards grouped under a single "postcards" heading, with the subject labels acting as the entry points. That means browsing is a matter of choosing a theme, not typing a query.

  • People-based categories — Bathing beauties, Women, Men, Couples, Families. Use these when you want portraits or figure studies, or when you are tracing how a particular type of subject was depicted over the decades.
  • Subject-based categories — Mona Lisa, Architecture. Use these when your interest is a specific motif or a built environment rather than a person.
  • Media-based category — Film & tv series. Use this when you are looking for tie-in or promotional imagery connected to screen productions.

Choose a path based on what you need

If you want to… Go to…
See people as the main subject Bathing beauties, Women, Men, Couples, or Families
Follow one recurring motif Mona Lisa
Look at buildings and places Architecture
Find screen-related cards Film & tv series
Get a broad sense of the collection Work through several categories in turn

Because the categories overlap in theme, a card that fits "Couples" may also be relevant to "Families" or "Film & tv series." Treating the categories as complementary rather than exclusive will give you a fuller view of what the collection holds.

What to expect and what to check on the site

The available description of tgtc.org is limited to the collection's name, its multi-decade span, and the category labels. It does not document a keyword search, date filter, or advanced query tool. So:

  1. Open the site and locate the "postcards" section.
  2. Select a category from the list above.
  3. Browse the items within that category, then return to the list and try another.
  4. If you need to find something specific, check the actual pages for any search or filter controls before assuming one exists — the category list is the confirmed browsing method.

If your goal is simply to understand what the collection is, reading across several categories is faster than trying to exhaust one. If your goal is to find a particular card, the category that matches its subject is the most direct route, with the caveat that finer search options are not documented and should be verified on the live site.

Website Overview

Limited stack disclosure and few obvious backend markers suggest a more restrained public footprint. That reduces easy fingerprinting clues but is not proof of overall security. An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality.

Domain and Registration

Registered in 2006, this domain has about 19 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses the common .org extension, which is not an independent safety signal.

DNS and Email

Nameservers are provided by srvnl.nl, indicating managed DNS hosting. MX records point to the tgtc.org email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed.

TLS and Certificates

The public key uses EC with 384 bits. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.

HTTP and Browser Security

The checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value LiteSpeed. No explicit CDN or WAF marker was found in the response headers.

Technology Stack Analysis

No obvious technology stack is exposed. This may reflect restrained information disclosure, although the underlying technologies remain unknown.

Search and Social Sharing

Open Graph is partially configured; og:image is missing. Twitter Card metadata is configured. The title has 42 characters, within a common display range. A meta description is present, with 81 characters. The observed directives allow indexing and link following.
