Late 60s/ Early 70s Red, White & Blue Enamel Flower Brooch

This is a wonderful red, white, and blue Americana enamel flower.  A layer of white petals sits on top of a layer of red petals. These unique petals are curved on one side and scalloped on the other. The petals curve back and down forming a dome-shaped flower.  A royal blue dome center finishes the look. This brooch measures approximately 2½” in diameter and closes with a locking C clasp. It is unsigned and in excellent vintage condition.
