Here is a brightly burnished and lacquered copper brooch in the form of the musical staff with a treble clef and a whole note. There is black anodizing to set the design off. The pin is signed "Renoir," a trademark used by Jerry Fels of Los Angeles during the mid-century years. His jewelry is Modernist in design and shows excellent craftsmanship. This fun musical motif pin is in excellent original condition with no scratches or wear. There is a tight safety catch as well. The pin dates from between 1950 and 1965. It measures 2 1/4" wide X 2 1/4" high.
