WWI German Regimental Beer Stein with lithopane image in the bottom of the mug. This is a very cool stein featuring the legendary German Zeppelin!This one is dated 1912-13 and is from the 1. Marine Luftschiffer Regt. (Tondern). I has a large Dirigible in the center with a bi-plane, submarine,and large sailing ship along the sides. The names of the members are listed down both sides next to the handle. It has a Pewter top with an Eagle mounting the peak, and a Lithopane of a soldier and lady in the bottom. The stein is 4 3/8" across the base and stands 11" tall. It is in excellent undamaged condition, and is unmarked by its maker. A very nice example of the German Regimental Steins representing a regiment not usually seen.
