The new Library of Congress Flickr page everyone's talking about is in fact incredible. And if you love looking at historical photographs of everyday Americans, the Library of Congress also maintains a massive database of photographs taken under the name of the Farm Security Administration, the New Deal agency that chronicled the effects of the Depression. Some of the later LoC Flickr photos are originally from this collection, which features legendary photographers like Man Ray and Walker Evans. My favorites? The vintage sideshow images.
