Antique lovable bulldog stick pin. It looks like bone but it might be celluloid. In either case, it's beautifully carved, giving this old dog a most expressive face. The worn black enamel accents the dog's features perfectly. The head measures 9/16" by 5/8" and the condition is very good with no chips or scratches. The 2-1/4" pin is gold colored metal and the extreme tip shows wear but the pin works fine.
