This is a Chase Blue Moon Cocktail Shaker set all in mint condition! It has the Blue Moon Cocktail shaker, 6 Chase Blue Moon glasses and the Chase tray, mint in original box. You know this was one of the oldest made because on the stamped bottom it shows “Patent Applied For”, never seen that before. According to my friend Steve Visakay's wonderful book this set was produced from 1935 to 1941 but this blue "shot measure ball top" was only made the first year so its rare and even rarer to still have it blue as most of the ones I have owned faded to a brown color. They all are shiny and bright inside and out and no dents, dings, plate loss or any flaws. All of the items are as close to mint as if you bought them today.
