Art Frahm!
Originally thought to be a Frahm, it turns out this is the work of an Art Pretender, Scott Pike.

But what Frahmage he brings to the 60s. He's learned from the master: note how the guys in the service bay 40 yards away can detect underwear hitting t he blacktop - and only someone steeped in Art's work could give these super-sensed lechers the classic Hang-On-To-Your-Hat! postures. It's a poor copy, unfortunately, but you get the idea. LUBRICATION. Get it? GET IT?

LET THERE BE . . . CELERY!
