Mid-Century Modern Industrial Age Brooch Copper Gold Black Vintage Jewelry
This interesting pin has two triangles on the top with goldtone and copper finishes, and a bottom circle featuring a gear cam and a black disk. If you look at the back, you'll see that the bottom of the pendant is affixed with a hexagonal nut. The pin measures 2-1/8" x 2" and is in excellent vintage condition. Quite unusual! It will be shipped in a gift box.
