just got done watching Super 8, which is a period piece taking place in summer '79, and sure enough - there's a bunch of wacky's in two of the kid's bedrooms
the one kid Charles has a nice line up of stickers stuck to the wall above his desk - I recall seeing Raw Goo, Dampers, Camals - they could be '79 reissues stuck there. There were several others scattered around - a Boo Hoo and a View Monster.
Most noticeable was the Gadzooka poster tacked on a wall. It even makes main stage for awhile, dead center in a scene between Joe and Charles as they're having an argument!!
the other kid Joe has a few in his bedroom too. several were ones stuck to the bed frame and then peeled away, leaving just the white paper ghosts on the wood.
He also has quite a few non-sports cards stuck to the wall - several star wars, a Space: 1999, and some cars.
plus, there's lots of 70's stuff that shows up all over the place. old comics, creepy, famous monsters, cheerios, frosted flakes, etc., etc.
