This tiny yet ornate sterling silver pin is a Blue Star Mother pin from World War ll. The blue star indicates that there is one son in military service. The pin is a mere 5/8 inch x 7/16th inch. The back of the pin is marked Sterling. The ornate sterling border enhances a white enamel background with a tiny blue star and thin red enamel stripe. There is a small flower on the top and bottom of the pin. There is a little hole in one of the flowers so that a chain guard or a military insignia could be added as desired. The pin has a simple C clasp.
