As part of FDR’s New Deal in the 1930’s, the Works Progress Administration created posters to promote the US’s various national parks. These posters are amazing, and the national parks now sell them in miniature form as postcards.
As an avid postcard sender, I’ve seen a lot of postcards in my day, and these are absolutely gorgeous.
You can search the interwebs if you want to see them — search “wpa national parks posters” in the googles. They’re all so good! Here are my favourites.
