Reader Grace Nunes kindly passed along a photo of a cool poster promoting the 1964 USAC stock car race won by A.J. Foyt. Nunes said her father purchased the poster in an antique store. Nunes is a hard-core racing fan herself and continues to watch open-wheel races in Central California.
As for the race in question, I pulled this detail from my Marchbanks history:
"The 200-mile season-ending race on Nov. 29, 1964, was called the Billy Vukovich Memorial and drew 6,500 fans and was televised on ABC's "Wide World of Sports." A.J. Foyt took victory, averaging 108 mph in a race full of spins.
"Joining Foyt in the 25-car field were legendary racers Ron Hornaday Sr., Parnelli Jones, Joe Leonard, Bobby Unser, Lloyd Ruby, Marvin Porter and Jud Larson (According to Ultimate Racing History, "Marvin Porter replaced Bobby Marshman, who was critically injured in a tire test in his Indy car at Phoenix the day before the race. Marshman died on December 4th in San Antonio, Texas.")"
Thanks, Grace, for letting me share this. As a reminder, this whole Marchbanks history is a collaborative project so if anyone else has photos, stories, maps, etc., feel free to share them with me.
