This is a pair of shot glasses by Hazel Atlas from the 1940s. Each is 2 1/2" tall and 1 3/4" wide. They are clear glass with red decoration. One side has a crest and the words Holland House Cocktail Mix Jigger, the other has measurements that lead from 3/8 oz or 1/4 jigger up to 1 1/2 oz and 1 jigger. They are marked on the base with a CCC mark, the C's are concentric nesting in each other. That stands for the Continental Can Co., the parent company of Hazel Atlas. They are in excellent condition with no chips, cracks, or wear to the decoration.
