US Army National Guard 148th Field Artillery Division World War 1 B&W Real Photo Postcard

This postcard features a group of Allied artillerymen alongside a French 75mm M1897 field gun, likely captured during the First World War in France. The French 75, as it was commonly known, was a groundbreaking piece of artillery due to its innovative hydro-pneumatic recoil mechanism, which allowed for unprecedented rates of fire.
