The original doors that hung at a garage in the Indianapolis 500 Speedway are to cross the block at Heritage Auctions.
They are expected to make in excess of $3,000 in the June 18 sale.
The doors were installed at some time during the 1930s and can be seen in period photographs. They have not been repainted since they were removed from the stadium in the 1960s.
Chris Ivy, director of sports auctions at Heritage, comments: "Little could be more evocative of the Indy 500 than these historically significant, vintage Indianapolis Motor Speedway doors.
"These hung at Garage #2 in the original Gasoline Alley area�Ǫwhat gearhead would not want this as a prize?"
Other lots on offer include a fire suit worn by the legendary Mario Andretti to win the 1969 race, which is expected to sell for more than $2,000.
It displays significant wear and tear and is accompanied by a letter of provenance from Andretti himself.
Indy 500 enthusiast Dr Harlan Hunter painstakingly assembled the collection over a number of years.
Ivy described Hunter's collection as the "most extensive of its kind in the world.
"For years, Dr. Hunter had access to the greatest drivers and race tracks in the world. In that time he amassed a deep and far-reaching collection of important race-used material."
