This is a single Baltic pattern Royal Ruby low footed sherbet cup or bowl by Anchor Hocking. It is 3 5/8" wide and 2 1/4" tall, in excellent condition with no chips or cracks. Royal Ruby was produced from 1938-1967, and some pieces were made later from 1973-1977. The vast majority of Royal Ruby was made in the 1940s. Please see my other items for more Royal Ruby.
