Howdy Mike!
Thanks for posting that - that is actually one of my scans that is now bouncing around the interwebs.
It is from my copy of a L-M Dealer Management magazine. Vol. 8, No. 3, September 1968 to be specific.
Below is the pic larger with the caption included.
I'd say there was a bit of bait-and-switch going on - that Cougar on the end is a GT and I doubt it could be had for so cheap.
I'm sure it's no coincidence they put a GT on the end.
