I have here for your consideration a Roseville Pottery shell shaped small dish or ashtray. This has the glaze color sea blue or similar color of light blue/green. Measuring about 5 inches wide by 5 3/4 inches long by 1 3/4 inches tall at the tallest this is a beautiful older piece of Roseville Pottery. As I was told these were unmarked except for a paper label which is long gone. I would consider this to be in very good condition with some minor manufacturing flaws including an unglazed spot along the edge and a couple of spots in the bowl of the dish that stick up like a piece of sand under the glaze.
