Forgive me for cheating at this one moment ... I created it 40+ years ago!
Of course, this was pre-computer ... I employed scissors, glue, colored pencils, regular pencil, white construction paper or cardboard and Sports Illustrated mags to clip from. The card front was inspired by the Topps 1964 baseball design, while the back was a rip-off of the Topps 1968 football design (but without the big cartoon). Here's the full set in my dresser drawer:
1 Tommy Nobis Falcons
2 Joe Namath Jets
3 Roger Stauback Cowboys
4 Ken Stabler Raiders
5 Archie Manning Saints
6 Tom Dempsey Rams
7 Terry Bradshaw Steelers
8 Larry Csonka Giants
I also found a clipped photo of Brian Sipe, but I never made a card from it ... we'll call that a proof, ha-ha.
