This very pretty light blue Radiance Cup and Saucer set was made by New Martinsville Glass from 1936 to 1939. The Saucer measures 5 1/4 inches in diameter. The Cup measures 3 1/4 inches in diameter at the top. Both the Cup and Saucer are in very good condition with no chips, cracks or scratches. We guarantee all items to be as described. THANK YOU.
