Nearly identical to the photo on the back page of the '69 Chevrolet Sports Department brochure.
Probably a late Styling car, when final striping/trim decisions are made. The car on the brochure is configured as a Z/28 with Style Trim but has a black grille and standard headlamp trim. Possibly the same car used for the "We've got a mean streak" print ad. Also seen in the showroom brochure, with the later rev depicted with a ducted hood.
The only known '69 Pilot build, a Z/28, was recently sold and is undergoing restoration.
