This 1970s brooch features a vibrant pinwheel starburst design crafted from enameled metal in a patriotic red, white, and blue color palette. The shape is an abstracted flower or firework starburst with a modernist aesthetic that really stands out. It measures 2.75 inches in diameter. Unsigned. One very small dot of missing color, as shown in the closeup. Does not detract. Your item ships the next business day after purchase.
