Super Bowl IV
I wasn't around yet, but since I'm from KC I had to show you the ring from Super Bowl IV, where the Chiefs downed the Vikings 23 to 7. Lenny Dawson was the MVP in that game.
Jewelry companies who want to enter the Super Bowl Ring competition start working with possible designs once they have an idea which teams might be contenders for the title. They don't present the ring designs until after the Super Bowl--they wouldn't want to jinx anyone's chance of winning.
