Corbis Images just launched “The Green Cabinet” – a Tumblr showcase and archive of beautiful and rare historical news photography. The Green Cabinet (named after the hundreds of original green-painted cabinets from the 1930s in which the UPI negatives are stored) allows user to experience the past through the lens of the photographers who lived it, some known and others forever anonymous. The collection contains more than 1,000 unique images from the Corbis Bettmann Archive and United Press International Archives.
