This little metal Yellowstone souvenir lapel pin isn't marked. I've seen similar pins in sterling but this one is goldtone. The coloring doesn't look like brass and hasn't tarnished so it may well have some gold content but without any markings I'm going to assume it's brass. The pin has a very Art Deco layered look, a bear in a circle over a winged arrow shape. Yellowstone National Park is printed on the top of the arrow and around the circle framing the bear. Attached to the chain is another, tiny layered arrow pin with the number 42. The main pin is about 3/4 of an inch high, the chain is 1-1/4" long, and the number 42 pin is 3/8" high. In excellent condition with no scratches or damage, the pin looks like it spent the last 70 years stored in a jewelry box. Price includes standard shipping in USA.
