This pretty marcasite pin has excellent detail with many open areas. It show a brown horse pulling a flower cart with green and blue flowers. The wheels and horse's hooves are black enamel. The pin is three dimensional; the horse is well-defined with lots of character. The only mark is "sterling" but the workmanship is superior. It probably dates from the 1970's. It measures 2" long X 1 1/4" high X 1/4" thick. It is in excellent original condition and does have a safety catch.
