DYNAMIC GEOMETRIC ART DECO BROOCH! Measures about 3 5/8' long and 5/8" wide. Barpin shape. Comprised of 6 ball shaped black segments attached to a white metal backing. "C" clasp. Heavy, well made. Hard to test for bakelite..I guarantee it to be an authentic art deco period piece, though it could be another earlier plastic or material. Not a lightweight plastic. All original, excellent condition, no damage or repair. From my personal collection.
