Real photo postcards from World War One.
This is interesting... I was always led to believe that soldiers' correspondence was encouraged not to tout the worst part of the war experience (but maybe this is a myth?) Were these kinds of postcards common?
Scenes of destruction are quite common. Not just damaged equipment and buildings but also dead horses,enemy corpses and skeletons. The more gruesome images were not mailed as they would not have passed the censor but collected by the soldiers as souvenirs.
