I have programs from Charlotte Motor Speedway for 1962 (National 400), 1963 (World 600) and 1964 (World 600). They are all in good condition. The 1962 is signed by Richard Petty, Bobby Johnson, Bob Welborn, David Pearson, Ned Jarrett, Fred Lernzen, Bunkie Blackburn and Nelson Stacy. Where can I find the value? Or, does anybody know? Thanks!
