Pro-circuit race car driver John Andretti, together with sponsor Window World, have set the bar for "The Greatest Spectacle in Racing." Andretti has been gathering signatures of every racer in the industry, travelling all over the U.S. in an authentic 2011 Dallara.

The car has also been decorated in the same outfit as the remarkable 1911 Indy 500 winner, the Marmon Wasp, according to Fox News. The signature-gathering event is said to serve as a charity auction for the St. Jude Children's Research Hospital, aside from it being a tribute to the 100th anniversary of the Indy 500.

 Around 249 of 273 drivers are expected to have already placed their names on the car, including the likes of Gordon Johncock, A.J. Foyt, and Mario Andretti. The other signatures that were yet to be imprinted on the car belonged to foreign drivers who were unable to visit the U.S., while famed 1960 Indy 500 winner Jim Rathman passed away before he got to sign on the car.

Andretti also wrote about his experiences travelling to track these drivers and convincing them to join the effort in his book titled, "The Stinger, Speeding Toward Hope," as per the news agency.

Fox Business also gave insight on John Andretti's Stinger race car, which is expected to fetch up to $1 million. Proceeds of the auctioned car, with all the signatures of living Indy 500 racers, would be donated in full to the chosen foundation.

"Window World has paid all the bills on it... Honda has donated a race-winning engine for it," Andretti said. "Firestone is donating the tires; We have a Scott Dickson seat in it... Barrett Jackson is going to be doing the auction."

The charity auction event is scheduled to take place on May 25 in Indianapolis, with all proceeds going to further treatment of kids living with cancer and future research studies, according to the publication.
