Can anyone give me an estimate of value for a vintage mechanical bartender. He holds a cocktail shaker in one hand and a martini glass in the other. When activated, he goes through the motions of shaking the shaker and pouring a cocktail into the glass. Then he drinks it and smoke comes out of his ears. I don’t know how old he is, exactly, but I remember my uncle having one of these when I was just little, so it would date back to the late 50s or early 60s, if not older. The original box is included and it’s in very good condition. Any ideas?
