When the winners began to be added annually after 1936, most were depicted wearing a helmet through 1970. Floyd Davis, who co-won the 1941 race with Mauri Rose, was depicted without a helmet, while Rose was depicted with one. By 1946, most were shown without their goggles. The likeness of 1957 winner Sam Hanks was the final one to feature goggles. The likeness of 1970 winner Al Unser is the last to be depicted wearing a helmet (by that time, drivers were wearing full-face helmets, so the feasibility of helmets on drivers was impossible). When he won again the following year, his 1971 likeness was shown with natural hair. It has been standard practice to sculpt a brand new likeness for repeat winners, including drivers who have won in consecutive years.
