A Wheaties Commemorative Edition cereals shadow box with John Elway signature (and one other signature, possibly Mark McGwire?). Signatures yet to be authenticated. Elway played his entire 16-year professional career with the Denver Broncos. At the time of his retirement in early 1999, Elway had recorded the most victories by a starting quarterback and statistically was the second most prolific passer in NFL history. He was also a prolific rusher of the ball, being one of only two players ever to score a rushing touchdown in four different Super Bowls (the other being Thurman Thomas) and the only quarterback to do so. Please see photos to review signatures and condition.
