Mid Century Modern Mixed Metal Enamel Belt Buckle Modernist Copper Brass Steel

This fantastic three tone metal and enamel belt buckle features an attractive abstract pinwheel or flower design. It is made of copper, brass, and I believe either steel or stainless steel, and enameled with transparent enamel. There is some tarnishing on the back which partially obscures the maker's label. The legible part reads "Group _A_____ Concepts". Other than the tarnishing, this buckle is in great condition. It measures 2" × 2"
