Nice vintage glass drink mixer with screw on lid (strainer is built into the lid). As mentioned in the condition description, this piece originally had a cover/cap that fit on top of the strainer, but it is missing.
Made by Hazel Atlas, the glass is ribbed along the bottom and has a swirling pattern of cocktails along with recipes.
