1965 Topps football card of Oakland Raiders center Jim Otto. Otto played 15 years for the Raiders and is a pro football Hall of Famer. The strange thing about this card is that Otto was issued jersey number 50 in Oakland’s inaugural American Football League season in 1960, but switched to the number “OO” that he became famous for the year after that, so this obviously was an old photograph used on the card. Amazingly, Otto was a Pro Bowler 13 times in his 15 year career, and was the AFL all-league center for all 10 years of the league’s existence.
