Drivers were given extra incentives during the early days of the Tunis Speedway track in Waterloo, Iowa. This one was for the first rollover in the main event and the driver would receive 50 gallons of gas, which around that time (early 50s) probably was about 20 cents a gallon? Not sure if car
#269 (driven by Al Runyan at that time) got the rollover or was the third place winner (optional payout)
