1970s Car Part Ad Brochure w/ Spokesman Astronaut GORDON COOPER

Description

This is a 1970s vintage promotional sales brochure advertising for the "G:R:Valve" air induction valve for cars, measures approximately 3 1/2" x 8 1/2", tri-fold (3 pages/6 sides), brown/white, and states the valve "may be legally installed on 1974 and older vehicles in California." The brochure features astronaut Gordon Cooper as the product's spokesman.
Condition
: Faint trace of handling; also, when printed the publisher used paper which was slightly larger than a #10 business size envelope when folded, so one edge has a 1/4" fold flap (this is visible on the left side in scan #3). See my listings for other unusual, interesting and fun vintage items.
Multiple purchases are combined with a single postage charge
. All items are shipped sleeved in plastic and packaged between sturdy cardboard.
