Wallace,
It's a great topic, and fits in perfectly here.
I have a bit of a collection myself, but the theme I have leans more towards LeMans.
I'm a sucker for Astons and Ferraris as well as Cobras. I have a long out of print Michael Turner print of the Shelby/Salvadori LeMans wining Aston DBR1. It was signed by Salvadori and Turner when I bought it, but I had Shelby sign it at Silverstone back in the early 90s or so. He told me then that he had the original painting.
I'm also a fan of Nicholas Watts. I have a bunch of his, mostly LeMans winners.
