The 1965 card back design was a first - the cartoon was at the top of the card back and it had the player's name. Almost every card in the set had a cartoon. Only players with really long careers ( and yearly stats) were skipped. Of the 24 base Cubs, just one, Lou Burdette, didn't have one.
The 1965 Cubs were young and not very good. Of the 23 cartoons, only nine mention an accomplishment from their major league career. The rest are from high school, college, or the minors.
