German Puzzle Mug Beer Stein Lithophane Woman Image mit Bodenbild For Sale

German Puzzle Mug Beer Stein w/ Lithophane Base of Half Nude Woman. Vintage but I don’t know the age. Weighs nearly 2 lbs. and stands 7” tall. On the sides says “Deutschland” and a thick paper sticker on front that says “mit Bodenbild”. Appears to have not been used. No breaks, no cracks, no chips. Manufactured holes in the stein rendering it, I guess, unusable for drinking (or is that the puzzle). When stein is held upward towards light, scantily dressed lady appears at bottom.
Sorry. Stein weighs 2 pounds and calculator accurately quotes shipping costs to your zip code.
