You can search through many of the FSA's 1600 color photos from that period at the Library of Congress site here:
http://lcweb2.loc.gov/ammem/fsachtml/fsowhome.htmlMany of the 160,000+ BW photos are there too. It's fascinating to look at the links for neighboring negative numbers, especially for the 35mm films, since you can see the actual shooting sequences. Roy Styker, the director, often "killed" 35mm negatives he thought unworthy of inclusion in the archive by punching a hole in the negative. Photographer John Vachon seemed to like to play a game of snapping a photo of the "accomodations" in all of the hotel rooms he stayed in while on the road, whether it was a chamber pot or a genuine flush toilet. Stryker hole-punched most all of these, but they still give an interesting perspective on life in the times.
Vachon also liked to capture graffiti on occasion. One of my favorites is a chalk drawing on the side of a railroad boxcar, from around 1938, depicting Hilter and Mussolini giving the fascist salute faced off with Uncle Sam returning a thumb-to-the-nose salute.
