The hobby has a name: deltiology
Collecting postcards has an official-sounding name — deltiology — but it needs none. At its simplest it is the habit of keeping the small rectangles of card that travel through the mail, and of hunting for the ones you do not have yet. People have collected them since the golden age of the early 1900s, when millions crossed the mail and albums filled parlors.
The reason the hobby survives is the same reason the postcard does: every card is a piece of a place, a moment of someone's journey, and a small work of printed design. A collection is a personal atlas — which is exactly why this website exists as one.
Decide what you collect
A focused collection is a happy collection. The classic frames are:
By place. Cards of a state, a coastline, or the towns of one region — the natural companion to the Old Route Retro atlas, where every location is already mapped to the postcards made for it. By theme. Lighthouses, railway stations, national parks, small-town main streets. By era. Golden-age divided backs, linen cards of the 1930s, modern photochrome views. By journey. A card from everywhere you have ever been — the travel-log collection, which doubles as a record of your own routes.
New collectors often worry about choosing wrong. You cannot: the best collection is the one you keep adding to, and the dating guide will help you tell one era from another once you hold a few.
Where to find cards
Old cards turn up in antique shops, flea markets, estate sales, and the boxes dealers keep under their tables. Online marketplaces have made hunting easier, and so has the Postcrossing exchange, which fills mailboxes with cards from strangers around the world.
There is also a second, newer shelf: modern cards made in vintage style. The designs in this atlas are exactly that — new illustrations in the spirit of old travel, printed to be sent and kept. Collecting them is cheaper than chasing rarities, and it has the same shape: you choose a place you love and keep the card that shows it.
What makes a card worth keeping
Condition is the first thing collectors look at, whether a card costs a quarter or a hundred dollars. Corners sharp or worn, writing on the back, a postmark that adds story or one that obscures the view — these details set value, and the value guide walks through what matters and what does not.
For a beginner the rule is simpler: keep the cards you would be glad to look at in twenty years. A card of your hometown from the 1950s will matter more to you than a flawless rarity of a place you have never seen — and both have a place in the hobby.
Store them properly
Paper is fragile, and a little care keeps a collection alive for decades. The essentials: keep cards in sleeves or albums made for them, handle them by the edges, keep them out of direct sun and damp basements, and never glue or tape anything to a card. If an old card arrives with its stamp still attached, leave it there — removing a stamp damages the card, and the stamp is part of its postal story.
Old cards deserve the same gentleness whether they are worth five dollars or five hundred. The vintage-style versus vintage guide helps you tell which is which before you store them side by side.
The modern twist: collecting places, not just paper
Postcard collecting has quietly merged with travel memory. Collectors now chase the places they have actually driven through, the scenic highways they have crossed, and the small towns they have stopped in — which is precisely the country this atlas maps. Each of the routes in the atlas is a ready-made collecting theme, and the Postcrossing guide shows how the same habit works as an exchange rather than a hunt.
Start small, start somewhere you love, and let the pile grow. That is the entire method.
What is deltiology?
Deltiology is the study and collecting of postcards. The word comes from the Greek for a small writing tablet, and it simply names the hobby this guide describes: finding, keeping, organizing, and understanding postcards.
What postcards are worth collecting?
The ones you care about — by place, theme, era, or journey — plus any genuinely old or scarce card in good condition. Rarity, subject, and condition drive market value, covered in our guide to postcard value.
Is postcard collecting expensive?
It can be nearly free. Boxes of common cards sell for little, flea markets price most cards at pocket change, and new vintage-style cards cost no more than a typical souvenir. The expensive end of the hobby is optional.
Where can I find old postcards?
Antique shops, flea markets, estate sales, online marketplaces, and the boxes under dealers' tables. Family attics are the classic first source, and the Postcrossing exchange supplies modern cards from around the world.
