 The trophy has been in use since 1936.A smaller replica of this trophy has been officially presented to the winner after the race since 1988 and team principal since 1997, usually in a press conference either at the Speedway or in Detroit at the North American International Auto Show at the BorgWarner exhibit, except for the 2011 race because of extenuating circumstances (the winning driver had died in a crash at an aborted INDYCAR race; the winning team principal and the driver's widow were presented with the respective trophies in the ensuing January).Prior to that, winners received a replica mounted on a chestnut plaque.
