This pin is a rocking horse made out of leather, and with a chain halter and corded tail. It is very old and rather fragile. The mane is also leather, and there are gold accents around the body and feet. Perhaps colored leather or a vinyl material, I'm not sure which. The brooch measures 3 x 2 inches, and it has an old-style C-clasp. Maybe an Elzac, but not marked, as many of his pieces were not.
