This may be
a one of a kind photograph of the 2nd Engineer motorcycle orderlies
at Engers, Germany. This scan is of a photographic print. It does
not come from a postcard. The motorcycles are Harley-Davidson. Note that not only is the 2nd Division Insignia painted on the motorcycles, but also the French Croix de guerre.
There is a second photograph of the 2nd Engineers with two motorcycles titled: Motor Transportation and R. S. O. 2nd Engineers # 324 If anyone should happen to own a copy of it, I'd be very grateful to have contact from you about it. My grandfather is in the photograph. I would very much like to have a copy!
