In the 70's, iron-on decals were immensely popular, as this was the decade for expressing your individuality. There were millions of them. There were even 'tee-shirt shops' that had, like, 2000 decals stapled to the wall. You would choose your decal and the tee-shirt you wanted to put it on, then the store employee would iron it on to the tee-shirt for you with a big steam-iron press. Whenever we would go on vacation I would always get a new tee-shirt with a decal on it. I seem to recall even receiving iron-on decals in cereal boxes.
