By Hazel Atlas, in the Ribbon pattern, these two 8" plates are from the 1930's. The green glassware fluoresces under a black light. Without chips nicks or breaks these plates remain useful to fill in as replacements if needed but have an unfortunate considerable amount of scratches.
Please see two sherbets in the same pattern listed separately. One of the sherbets is shown in one of the photos here.
