Injured driver & badly damaged vehicle from Kraftwagen Depot München, June 1915
Lengthy letter on reverse (see below) dated 29.6.15 with postage cancelled at München the same date.
The sender is a driver attached to Kraftwagen Depot München.
At this stage I'm unaware of the circumstances of the incident that caused the injuries to man seated on the vehicle's running-board, however it looks like he's lucky to have escaped with his life.
Given the date and location the photo was taken, it was unlikely the injuries / damage caused was the result of combat.
