This charming, ceramic piece measures 10 inches diameter. It is flat with the outlines of the buildings and clouds cut into the clay. I purchased the piece at a local estate sale, and added the hanger on the back. I don’t think it was meant to be a trivet, as the ceramic is not very thick or chip resistant. It is in good condition with no chips or cracks. Signature on back looks to be an L M or ML with B21.
