Vintage lidded stein in German Beer Stein Music Box: Clever and fun, this unusual beer mug is sure to bring on laughter. Every time you raise the glass to take a swig of beer, a rod on the base is released and the music box comes to life. I do not know the tune but it is charming. In very good vintage condition, the lid (which appears to be aluminum) is shiny and the mechanism secure. There are no chips or cracks, and the music box is in tact. It measures 4" in diameter and 8 1/2" in height (10 x 22 cm) and was made in Japan Attached a video
