Extremely scarce vintage Jack Johnson 1915 boxing exhibition 2 sided program. The program is from Argentina and is printed in Spanish. Exhibition was billed as "Celebre Campeon Mundial De Box" January 9, 1915 at the Casino Theatre, Buenos Aires, Argentina. Events to take place included punching ball, medicine ball with partner, shadow boxing, demonstration with partner on how to box, cinematic fight film of Jack Johnson, and 6 rounds of exhibition boxing. Program is in overall very good condition with wear to outer edges. This example is perhaps the only one known.
