Here is a dainty little gold-filled koi to wear on your lapel. It is of cast construction and marked "Napier," a premier mid-century American jewelry manufacturer. The quality of manufacture is excellent. This pin measures 1 5/8" X 1 1/4" X 1/4" thick with a three-dimensional quality. The finish is shiny and without blemish; the pin is in excellent original condition with a safety catch. It is around 50-70 years old.
