The Library of Congress had paired up with Flickr to post over 3,000 archived photos. There are two sets, one a color set of photos from the 1930's-40's, which this one came from, and the other a black and white set taken in the 1910's mostly of NY city.
This is a really amazing photo project, especially for lovers of history like me. There are lots of "Rosie the Riveter" type shots which are fun to see. A lot of the comments people are leaving include personal memories of family members that I find just as interesting as the photos themselves.
I've only looked at a fraction of the color set from the 30s-40s, but there have been photos of farms and farmers in Nebraska, Texas, Montana, mines and scrap heaps, women working for the war effort, and I've just come upon a series from a Japanese interment camp in CA.
I chose to post this portrait because it is so haunting. Amazing photograph, don't you think?
