Alan Ameche won the 1954 Heisman trophy and landed with the Colts a year before Johnny Unitas came along.  As a result, he played on two NFL Championship squads and was a participant in the 1958 finale, a game for the ages as it turned out. He's signed an EX-ish looking 1955 Bowman card in what looks like fading blue Sharpie, leaving a ghost-like autograph that somehow works in this instance. PSA/DNA Authentic is the grade for the signature.
