The first set to ever have logo cards - 1974-75 Topps Hockey
I believe that is the case. I do not recall any Topps (baseball, football, basketball or hockey set to have a logo card in it until this set). I do not recall any Fleer (football, baseball or basketball set) or any Philadelphia football set having logo cards. Team cards yet but not like the card above. This set had the Capitals card and the Kansas City Scouts expansion cards in it.
