Browsing through the list, I’m learning about things I never even knew I was interested in. Among the gems:
The Penny Postcard Archive has hundreds of scans of pre-1940 postcards, organized by state and county.
The Lost Formats Preservation Society documents data storage methods gone by the wayside. (You surely know the eight-track, but do you know the four-track?)
In the Pre-and-Post War American Advertising Galleries you can view more than 7,000 ads from 1911-1955 divided into the categories of beauty and hygiene, radio, television, transportation, and World War II.
The WPA Calendar Project shows off the gorgeous 1939 calendar created by the Federal Art Project.
And just for fun, the Condiment Packet Gallery.
