To the best of my belief that is not a factory brochure. It is an item someone printed up later in time just to sell commercially.
I picked up one several years ago. I can't remember but it could even have been sent to me as junk mail, selling the series of sheets on cars. I think it is one of many "spec sheets" on cars, similar to the old musclcards baseball cards that were made in the 90's. In any event, it's pretty nice so if you find one, you'll want it. Paul
I bought one of those printed items a few months back. I thought it was well done even if not an "original" sales brochure item. I like collecting little things like this to add to my collection of "X" related items. I did buy an original Buick GSX sales brochure from ebay recently. It is very interesting to go back in time to the early 70's just by reading and admiring the art design and layout of the era. This piece uses pen-and-ink illustrations for all the various features highlighted about the cars, as opposed to actual photos. It's a really nice piece.
