15 cm schwere Feldhaubitze 1902

A crew with their 15 cm schwere Feldhaubitze 1902. A heavy field howitzer that was in the German arsenal at the beginning of the war.
This card has the name Lancelot Willison written on the back. I found a record of a US Army veteran with that name buried at the Cypress Hills National Cemetery. Perhaps he brought this card back with him after serving overseas.
