Official National League (Frick) baseball signed by Jackie Robinson. This ball has a unique provenance. It originates from the family of one of the film producers of "The Jackie Robinson Story," which was released in 1950. According to the family, this ball was signed by Robinson on the set during the production of the film. Robinson's signature has been scripted in blue ink and grades 6/10. The remaining five names written on the ball, which are those of members of the 1950 Brooklyn Dodgers, ARE NOT the player's signatures according to PSA. They all have been scripted in an unknown hand. The ball displays light age toning and is in Excellent to Mint condition overall. Full LOA from PSA (for the Jackie Robinson signature only).
