Stamped: Louis C. Tiffany Studios Furnaces, Inc./ Favrile/ 325 and 329. Each round plate has a raised rim decorated with yellow and red enamel decoration in a repeating quatrefoil pattern. c. 1920 W 9.5/8 D 9.5/8 in. Note: these obviously sat in a cabinet for the last 80 years...we have not even tried to clean... I like the patina, but I'm sure they will clean up..
