Up for sale is a highly collectible, guaranteed 100% original 1930s \"Bottoms Up\" novelty shot glass produced by the renowned McKee Glass Company during the Prohibition era.

This iconic Art Deco piece features a molded, risque nude female figure. True to its classic speakeasy novelty concept, the glass is designed with a rounded top and no flat base—forcing the patron to completely finish their drink before placing it upside down on the bar.

This piece features McKee\'s highly sought-after, opaque creamy yellow coloration historically cataloged as \"Seville Yellow\" (often referred to by collectors as Caramel Slag, Caramel Beige, or Custard Swirl).
