And now we have photographic evidence to support my claim - an actual vintage JC Penny print ad showing Super Dennis engaged in some deep knee bends in JC Penny "Super Wear Headquarters." Some guy is auctioning this torn-out ad on ebay for $11.99. A tad steep for my tastes, but I'll starve him down then make a rock-bottom "best offer" (hot financial tip - the putrid economy has also escorted us into a golden age of haggling).
Man, I wish I could read that copy, but it gets too blurry when enlarged. Once again I am tantalized by Super Dennis! On the bright side though, I think I just found my next Halloween costume.
Another thing you will note is that the actual photo and the sticker graphic below don't look very much like one another. The heads sorta match, but the impression I'm left with is that the sticker graphic was the original concept, and the actual prop is the result of budget realities settling in. In any case, pretty sloppy synergy there in the JC Penny in-house ad department, I would say. And at first blush the sticker looks cooler, but upon further study I like the photo version more. Probably because that's how I remember him from the TV spots, but those HVAC flex-tube arms and grappling hooks he has for hands don't hurt either.
