The 31st International 500-Mile Sweepstakes was held at Indianapolis Motor Speedway on Friday, May 30, 1947. It was the opening round of the 11 races that comprised the 1947 AAA Championship Car season. The 1946 winner, George Robson, had been killed on September 2, 1946 in a racing incident. Driver Shorty Cantlon would be killed in an accident during the race.
Beginning in 1947 the Speedway issued "Bronze" and "Silver" badges. Bronze badges allowed gate and garage access during the month and silver badges did the same but also allowed pit access. On race day, one needed a Back Up Card Early bronze badges were indeed bronze, but silver badges were only a silver colored pot metal. Bronze badges began being made of a bronze colored pot metal sometime in the late 1950s or early 1960s.
