Vintage Pin / Brooch - Member Services Star - Esco Milwaukee

Vintage Pin / Brooch - Member Services Star - Esco Milwaukee Measures about 0.75". Some marks to rear. Not sure if very dark blue or black. Preowned vintage brooch/pin, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated. I ship quickly and provide tracking information but delivery times are an estimate. Item is located in the United States. Country of manufacture cannot determined.
