Until the Lombardi Trophy, there was no such hardware for the NFL champs. So, in 1963, deciding in their infinite wisdom that the Bears (who beat the New York Giants 14-10 at frigid Wrigley Field to win it all) deserved some prize, Mayor Richard J. Daley and the Chicago City Council commissioned this trophy. They named in honor of President Kennedy, who had been assassinated the month before. The trophy is at the Chicago History Museum on long-term loan from the Bears.
