Over at srsly cool, rare color photos from World War I have been posted.

Little is known about each individual photo, they are believed to be digitally coloured. During WW1 colour photography was in it's infancy, pioneered by photographer Jean-Baptiste Tournassoud using Autochrome plates invented by the Lumiere brothers. These photos are either digitally remastered or works by Tournassoud.

Update: I originally located these photos at a forum but thanks to digg have since found a more descriptive source. I have updated the information on all of the photos but sadly the real details for most have been lost in time.
