During the 1968 Baltimore Colts season, Morrall filled in for an injured Johnny Unitas leading to an NFL championship shutout victory and Super Bowl III, which they lost to the New York Jets. For the 1972 Miami Dolphins season (both under coach Don Shula) he filled in for an injured Bob Griese leading to Super Bowl VII and the only perfect season in NFL history. Morrall made Pro Bowl appearances following the 1957 and 1968 seasons.
This Miami Dolphins mini helmet was signed in blue by Morrall and inscribed, "#15 QB" and "1972 17-0." This mini helmet includes a JSA sticker and COA.
