Racing fans around the world have another opportunity to assist the family of Justin Wilson, the INDYCAR fan favorite driver who died in an August 2015 crash.

Paul Zimmerman, owner of racing memorabilia store The Motorsport Collector, is offering a silent auction of eight 16x20 prints depicting the start of this year’s INDYCAR Grand Prix at The Glen.

Each print is signed by all 22 starters from the season-ending GoPro Grand Prix of Sonoma – including Sonoma winner and season champion Simon Pagenaud, three-time Indianapolis 500 winner Helio Castroneves and past Indy car champions Sebastien Bourdais, Scott Dixon, Ryan Hunter-Reay, Tony Kanaan, Juan Pablo Montoya and Will Power. Also signing each print were greats Mario Andretti, Dario Franchitti, Rick Mears and Roger Penske.

It’s a mind-boggling set of driver autographs for race fans, considering the elite group has totaled 24 season championships, 17 Indianapolis 500 triumphs and 300 Indy car race wins. And those numbers don’t even include the 14 championships and 16 Indy 500 wins achieved by Penske as a car owner.

The silent auction for each 16x20 print starts at $500, with Zimmerman accepting bids by email through 1 p.m. ET Dec. 24. Get more information and place a bid by clicking here.

All proceeds go to the Wilson Children’s Fund, set up to help care for Justin’s widow Julia and their two daughters. Winning bidders will be able to pay through the fund’s PayPal link and receive free shipping of the prints.
