Kristen,
Shelby signed it for Tony when he was at a Shelby event. The guy with the crutches is Vaughn Cartwright. He is an amputee and has won a couple of World and several National Arm Wrestling Championships before he retired. He also ownes Shasta Dental Labs but has mostly turned that over to his son. The GT-40 is his as he is building it to show. He has a really nice black Cobra in the garage with silver stripes that he hasn't driven in probably 2 years. He normally doesn't use crutches but has an infection in the stump of his leg from where the prosthetic leg rubbed it, so they must have messed up the fit this last time as he has to go in every year to have it checked and fitted if anything has changed.
