This is a superb grouping of 55 original 8 " x 10 " or 5 " x 7" Sports Car "Hero Cards" all hand-signed in person for me at IMSA sports car events at Daytona, Road Atlanta and Virginia International Raceway (VIR) over the past 25 years. Each card comes in a plastic sleeve and they all are in a red 3-ring binder; ready to enjoy. I use a * to denote really famous, top-notch sports car drivers. 

There are 134 signatures, with all cards signed by two, sometimes three or more drivers.
