Fabulous cat, could be the Cheshire Cat from the fairy tales, and he is done in lovely enamel in quite fine detail on what looks like brass base metal. The detail is amazing on his face, even down to the whiskers ! He measures about 1 & 1/4" tall and is in wonderful condition. This is an old item, I acquired it over 25 years ago from an antique jewelry dealer. There is a hole pierced in one of the cat's ears for hanging from a chain. A most unique and rare piece.
