I came across this very interesting project :

The Commons on Flickr
The key goals of The Commons on Flickr are to firstly show you hidden treasures in the world's public photography archives, and secondly to show how your input and knowledge can help make these collections even richer.

You're invited to help describe the photographs you discover in The Commons on Flickr, either by adding tags or leaving comments.*

Have a look at these beautiful pictures from the The Library of Congress

"These vivid color photos from the Great Depression and World War II capture an era generally seen only in black-and-white. Photographers working for the United States Farm Security Administration (FSA) and later the Office of War Information (OWI) created the images between 1939 and 1944."
