I think this is what led to my purchase, two weeks ago, of my TJ.
That ad, either for Malboro or for Jeep, was in Ski magazine. Mountain landscape, winter scene, red CJ in the middle of a snow field, doors off and windshield down, with a husky dog in it. Sitting on the hood, I think, a cowboy smoking -- which makes this definitively a Marlboro ad. The copy was "something something to Marlboro country".
Can't seem to find it on the Intertubes.
