My buddies that work at John Lance Ford in Westlake, OH have a B&W 'lot shot' like that from around then as well hanging in their parts/service department... Might be a couple of years later, though... I'll see if I can get a pic of the pic the next time I'm at the dealership (or get one of them to take a pic of it for me...)
My buddy Terry (who has worked at Lance Ford since '76) almost bought a used '71 Cougar GT 429CJ off the used car lot there in '74, but bought a '73 Mach 1 351C-4V - 4-spd from another dealer... which, of course, he still has...
