Just like us, the Library of Congress has a flickr account. Unfortunately for us, LoC has kicked our behinds when it comes to content. They have over three thousand photographs from their collections for all the world to view, admire, study, and best of all – use. The best part – the photos are from the first half of the twentieth century (1910s-1940s), which means that the copyright has expired. That means you can use these pictures any which way you’d like. Of course, make sure you still credit the photographer (if known). The flickr account also nicely compliments the American Memory Project that the LoC does.
Thanks to Kelly for the link!
