Philadelphia Jack O'Brien (born Joseph Francis Hagan) was one of the most skilled and cerebral fighters of boxing’s early 20th-century era. He held the World Light Heavyweight Championship and famously fought a gruelling draw against heavyweight champion Jack Johnson in 1909. The pin offered here is marked, "Our Champion", "Young Jack O'Brien", and shows the light heavyweight champ in a boxing form. Made by J.H Shaw and Co., this pinback is a seldom-seen example.

Size
1.5" Dia.

Condition
The pin is in excellent condition with only minor edge wear.
