The 29th International 500-Mile Sweepstakes Race was held at the Indianapolis Motor Speedway on Friday, May 30, 1941. The start of the race was delayed due to a fire that swept through the garage area on race morning. No persons were injured, but one car in the field was destroyed. The race rolled off with only 31 cars, and ran to its scheduled distance. This would be the final "500" prior to the United States involvement in WWII. It was not known at the time, but it would be the final race organized by Speedway president Eddie Rickenbacker, and due to the war, the race would not be held again until 1946.
The 30th International 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway on Thursday, May 30, 1946. This was the first Indianapolis 500 presided over by new track owner Tony Hulman. The track had closed in late 1941 due to World War II, and over the next four years, the facility fell into a terrible state of disrepair. Hulman purchased the Speedway in November 1945, and quickly went to work cleaning up the grounds, which had become overwhelmed by overgrowth and weeds. The Speedway re-opened, and the 1946 race was considered a rousing success.

Shaw took home $31,875 in prize winnings, plus additional prizes that included a car and a refrigerator.
