Lovely, vintage, glass condiment, candy, or nut dish. Pretty opalescent blue in color, graceful curves, shell shape. I do not know the maker, their are no marks. Measures a petite 6 and 17/8 inches long and 5 and 7/8 inches wide. A tiny bubble under the surface that looks like a chip but is not, some light wear marks on the bottom where the dish meets the surface. No cracks, chips, or dings.
