These things were all over comic books in the '80s. Prizes/Cash schemes like this were a dime a dozen in comics, but Olympic is one of the most memorable, for me, because of the super hero in the upper left. That dude always looked awesome, so I was always drawn to the ad. But I never tried any of these things because I was way too lazy to sell seeds or cards or stationary door to door.
Visually appealing ad, though. I assume the super hero's name is Olympic. Or maybe Capt Olympic? Olympic Man?
