In post #11 there is this picture of cars along with drivers. The same picture appeared in a two-page advertisement in the April 1967 Car and Driver. I've scanned the ad and at the bottom, the drivers and their cars are identified.
Thomas, thank you for posting these fantastic pictures! I am struggling to decide if the coolest is this picture, the Mustang and Cougar Prototypes or the Ford GT at LeMans in the rain taken from the air?
