Len Dawson attended Purdue University and went on to play for three professional teams, most notably the Dallas Texans/Kansas City Chiefs. Dawson led the Chiefs to three American Football League Championships, and a victory in Super Bowl IV (at the time, it was labeled the AFL-NFL World Championship game), for which he won the game's MVP award. He was inducted into the Pro Football Hall of Fame in 1987.

This Riddell full size replica Kansas City Chiefs helmet was signed in silver by Dawson and includes a JSA sticker and COA.
