So, let's say you're 1969. How do you sell a suit to potential customers with loads of cash who insist on following the latest cultural departure from reason? You put your suit on a handsome dude and build a 1/4-inch plywood Peter Max holiday pantomime, of course. Grab a pretty model from your file cabinet full of headshots and paint her face like a trippy, puckish nymph. Wait. A prop. We need a prop. Eyeball cutout on a stick saves the day!
Advertising complete! Zeitgeist captured! Now, just put your feet up on your desk, blow a jay, and wait for the art direction awards to start rolling in.
Oh, by the way. $99.50 and $120 are about $100 and $600, respectively, in today's modern Futurebucks.
