Circa 1932 - 1939 featured is a Federal Glass Co. amber Madrid hot dish coaster with indent. The coaster measures 5" in diameter with a 2.5" circular indent to hold a glass. These coasters are very hard to find. There are two available in excellent shape and one with a small 1/4" shallow chip on the rim. The chipped one will be quoted individually on request. The color is a very delicate light amber, almost yellow.
