PASJDHal I dunno what dates them to 47 but it hardly seems surprising given the publicity and notoriety surrounding Robinson, and I believe it was known well in advance of the season that he would be playing for Brooklyn, that a manufacturer would have included him in a set even if he hadn't established himself. EDITED TO ADD: As for dating them, is there anyone in the set who retired after the 47 season so it is unlikely they would have been included if the set was really 48?
