Official National League (Frick) ball signed on a side panel by Jackie Robinson and Tom Brown. Each signature has been boldly scripted in blue ink and grades 9/10. Robinson and Brown were teammates on the Brooklyn Dodgers from 1947 to 1951. Assuming the ball was signed by each player on the same date, this represents an early Jackie Robinson signed ball and one that could possibly date to his historic 1947 rookie season. The ball is moderately soiled, with a few light abrasions, indicating that it may have seen game use. In Very Good condition overall. Full LOA from PSA.
