Some eras in history seem only to exist in black and white. It's so rare to see a photograph from the 30's or 40's in color that it's sometimes easy to forget the the world was full of vivid color at that time. Every time I watch old black and white movies I wonder what color all the beautiful silk dresses are and what color the walls are painted. The Flickr photostream from The Library of Congress changes all of that. Loaded with scans of color slides from pre-WWII to the late 40's, it showcases the world in all its full color glory. The images range from Rosie the Riveter war workers to poor Southern share croppers to (some of my favorites) small town carnivals. They give a whole new perspective on what the world looked like at that time.
