This 11-1/4" crystal plate is in the Martha pattern by Cambridge, made in the 1930s. The rim has large and small flower-petal like scallops, the center has a daisy-like flower in reverse relief. My book calls it a cake plate but there's a 3-1/2" diameter ring in the center - I think it's an underplate for a dish or bowl, or some other type of serving plate. Despite my bad photo, the plate is crystal clear and in very good condition with one nick or short scratch on the underside and a few very light, fine use marks on the top. Those white specks in the photo are from glare or dust, they're not on the plate.
