This is a stunning vintage Art Deco relish tray or celery dish. It is marked RS Tilowitz. This mark was used by the Reinhold Schlegelmilch factory at Tillowitz from the 1920s to the 1940s. The mark is in green which dates this item most likely before 1936. This factory was closed by the end of World War II. The design on this piece is pure Art Deco and it could function nicely as an appetizer dish or even a vanity tray.
It measures 14 inches by 5 inches and it is very shallow. It is in excellent condition with no chips cracks or damage.
