Vintage 1930's Carved Black BAKELITE Pin Brooch

Here's a great example of old 1930's genuine carved Bakelite in a color that's hard to find...black. This pin is heavily carved with thick-petaled roses in an openwork carved-through design. It's a big one...3 1/4 by 2 inches and 1/4 inch thick! Back has the original imbedded 2-piece pinback with safety-catch closure. Pin is in excellent condition. First time offered from my personal 40-year collection.
