A rare Tiffany & Co. Essex Crystal (reverse painted) brooch circa 1930. The detailed portrait is a Doberman Pinscher with a little bell suspended on his collar. It is very finely exicuted and the Doberman is realistic. This piece has a simple gold frame with a pin attachment mounted on the back and a clear Tiffany & Co. stamp. This pin measures 1" in diameter and is in condition consistent with its age but overall very good.
