This vintage (1930-1950) brooch features a running horse inside a racing plate horse shoe. The shoe has nails in the “Lucky Seven” pattern, which generally dates a piece as 1940 or earlier. It appears to be brass, but it is unmarked. It closes with a modern, rolling/locking C clasp. It measures 2” x 2”, so is a real statement piece that would look great on a scarf, on a coat lapel or on a hat.
