This is a vintage sterling silver and enamel brooch or pin. It has BROTHER IN THE SERVICE across the front. It is marked STERLING on the back. The pin has red, white and blue enameling on a shield. The pin measures 1-3/8 inches by 3/4 of an inch. The pin is in very good condition but does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
