Here is a 1970 Valvoline ad featuring the 1970 Chaparral Camaro. It appeared in the program for the October 4, 1970 running of the Mission Bell 200 at Riverside International Raceway, Riverside California. It's interesting to note that their are no front or rear spoilers on the car, so the picture must have been taken early in the year, perhaps in testing at Hall's personal test track in Texas. I wonder if this ad appeared in all of the Trans Am programs throughout the year? The ad also mentions Jim Hall as a driver but by the time this ad appeared in this program, he was no longer the driver of the car. This picture appeared in a thread on this website.
