Unbelievable Matisse Renoir Copper Leaves Pin. This awesome piece has two leaves with enameled coloration on each that is set on copper metal. This pin is in excellent condition with no wear to the enamel or copper at all. The great design was intricately made up by the wonderful makers at Matisse Renoir. The back of the pin shows this with a very sturdy pin clasp that latches at the smaller flower that is signed "Matisse c. Renoir" in visible lettering. This flower pin measures 3 1/8" long by 1 3/4" wide. This is a very simple but very gorgeous piece.
