I remember seeing this picture one day.
This group picture of some soldiers was taken in 1919 so no photoshop has been used here. The photographer didn’t see that shadowed face when the picture was taken. First later some of the soldiers saw the picture and recognized the face as a fellow soldier named Freddy Jackson, who died in an accident caused by an airplane propeller two days earlier. If it’s real I actually feel sorry for that poor guy.. He still thought he was alive and wanted to be part of the group photo.
