This set of 6 coasters or mats are enameled metal on cork backs. They were made in England by the Metal Box Company. They once cost 8/3. They are unused and in the original box although it is not in great shape. The coasters are perfect. These are quite vintage, probably from the 50s.
Each coaster shows a ballerina in pink tutu executing a different dance step. Rose adagio, Pas de chat, and Arabesque. They are 3 5/8 inches.
