This is a coveted Chase Blue Moon Cocktail Shaker set in good condition. It has the Blue Moon Cocktail shaker and 4 Chase Old fashioned cups. It also has the four matching Chase muddlers/stir sticks with with black Bakelite/Catalin tips and a nice round pattern on the bottom portion.. According to my friend Steve Visakay's wonderful book this shaker was produced from 1935 to 1941 but this blue "shot measure ball top" was only made the first year and it has faded to more of a brown color. There is some wear that can be seen in the pictures but it is a nice old set at a very reasonable price.
