Major League Baseball institutes the rookie card logo rules and the shrinks the number of baseball card manufactures to 2. For the first time a major sports league tries to influence the card manufactures and create rules for rookie cards (the cards drive the hobby). Well I can say it was not really a great success as Bowman was still allowed to print cards of players who were not in the majors. It was at least some attempt to try to standardize the rules. The rookie logo cards would have more meaning if less sets were made but everything can't be perfect.
