There are lots of designers that sell postcard series, but I love it when series are even more local, even if that means they’re only available in one region. Maybe it’s hard to differentiate from normal tourist cards, so here are some examples of what I was thinking about:
A county in Kansas recently released a local postcard series done in the old WPA parks/vintage travel poster style of postcards. They’e not places tourists would normally want postcards of (they’re just local parks) but artists were specially commissioned to highlight local attractions.
Oregon had a tourism campaign in 2019 that had a lovely series of free postcards called Only Slightly Exaggerated. These ones were more for general tourism, but the theme was very specific and as part of one campaign.
In a town nearby they have this alphabet series called ‘Faces of Lo’ . All 26 postcards show a letter with something very specific for the town ‘Lochristi’, ‘Lo’ in short.
There’s a series of illustrated Tucson, Arizona postcards that I really like! I get them from random gift shops around town, a lot cheaper and easier than buying them online.
