1957 Topps #142: John Martinkovic
Team: Green Bay Packers
Position: defensive end
Hometown: Hamilton, OH
Honors: Packers Hall of Fame
There is a nice array of photos of John Martinkovic on the Packers Hall of Fame web site. The last image looks like a prototype for a 1955 Bowman football card. Martinkovic did not appear in the 1955 Bowman set, but compare the image to Floyd Reid's card.
