Metal Polishers Buffers Platers & Helpers Intl Union 20 Years Pin

Found this old union pin from the Metal Polishers, Buffers, Platers & Helpers International Union. It's a 20 year service pin with a cool shield shape and some blue and white enamel work. Definitely has some age to it but the lettering is still pretty clear. Cool little piece of labor history if you're into collecting vintage pins or union memorabilia. It's small but has a good weight to it.
