Vintage Decanter with Shot Glass Stopper

Unique blue Bristol glass vintage (1930's or 50's) decanter with shot glass stopper. Bottle has faceted design, crown like stopper is a shot glass (for measure I imagine). Handpainted (beige or pale yellow/maze color, specs of gold and red) shiny gold ring at bottom and rim of crown like stopper. Bottom marked with number 40, 8 1/4" tall with stopper and 3 1/4" wide at bottom. Beautiful condition but some gold worn.
