This is a hard to find vintage piece. This pin has a reverse carved, clear Lucite base with a black, bakelite horse silhouette on top. It measure 2 1/8 inches by 1 5/8 inches wide. The c clasp pin is set into the Lucite.
The pin is in great condition. There is some minor surface scuffing expected with age. There is also a bit of glue around the silhouette, but I feel like this can be removed.
