Vintage Hand-crafted German-made Beer Stein Music Box

Large vintage hand-painted German beer stein with a silver-toned attached lid It is a glazed ceramic mug and in very good vintage condition. This stein actually has a music box in it built into the bottom of it. It is in working order and it's a German song that plays, but I'm not sure how long it will last because of its age. It seems to be in very good condition.
