From the "here's one you don't see everyday department", comes this Jackie Robinson and Roy Campanella dual-signed ONL/Frick mini-baseball. Likely a salesman's sample, this vintage ball has a diameter of slightly more than 2". The Spalding factory labeling stamps are moderately faded, however they retain enough integrity to be instantly recognizable. Hall of Famers Robinson (d.1972) and Campanella (d.1993) were teammates with the Brooklyn Dodgers from 1948-1956, and this scarce mini-ball (VG-EX) had to have been signed during that period, as Campy's ("6") strength signature is definitely a pre-accident example, while Robinson's autograph has softened over the years to ("5-6") strength.
