I found some more great Trans Am pictures on Flickr. Someone named "Carrera RSR" posted 65 color photos of Trans Am events held at both Laguna Seca Raceway and Riverside International Raceway. The pictures are mixed up but they include shots from 1969, 1970 and 1971. I will post the photos of the Camaros here but click on the the following link to see larger versions as well as the rest of the fantastic pictures:

These first 4 pictures were taken at the Trans Am event held at Laguna Seca Raceway in Monterey, California on August 24, 1969.
