To commemorate the AFL and NFL merger of 1970, the 1971 Topps football card set delivered a bright and vivid design that helped collectors easily distinguish between players from each conference.
Red borders surrounded AFC players while NFC players found themselves in a sea of blue.
Oh, and All-Stars had borders that were divided by both red and blue.

Condition issues aside, though, it's a fantastic set loaded with Hall of Famers and key rookies.
And in this guide, I'll run through the ten most valuable.
