Reverse Painted dogs

Edna Lewis studios revers painted dogs on convex glass. 4.5" diameter. It has wear on the backside and a long the edges but is still a very nice display piece. Also a very minor scratch on the glass as seen in the pictures. I believe this is from the 1930s(Please correct me if I am wrong)so it is very close to being 100 years old so wear is expected on such an old delicate piece.
