This is a large-format photograph measuring 4 1/4″ x 6 1/2.” It shows the ground crew of an aloft observation balloon. We see a truck and trailer. From the trailer we can see the cables attached to the balloon, which is flying overhead. Most of the crew is gathered around the trailer. Mounted in the truck’s rear are two machine guns for the balloon’s protection. The machine guns are manned. On the reverse is a penciled description, and what I believe is unit identification (Ballonzeug Nr 221).
