Can anyone suggest a Gridiron Greats or other article to learn more about this set? I recently added one to my collection although I don't have it in hand yet. I know its a multi-sport set with two football subsets and that collectors were expected to develop these themselves so I'm guessing they didn't know what player they got until the card was developed which is kind of cool. I also believe its the first Topps set of any kind? Thanks.
