I recall that in my 1970s childhood, the back of my bedroom door was covered with stickers that featured comical advertisements for fake products, parodizing or satirizing real products. I can’t remember, though, what these stickers were called or how one obtained them. Did they come with some other product? I’d love to have a set again. Have they ever been reproduced?
I had 'em when I was a kid. 
Yup. Wacky Packages. They were sold like baseball cards, came with several per package, and included a stick of gum. Very popular in the 70s.
Cool. Anyone know whether any replicas have been produced? I’d like to have them for nostalgia’s sake, but I’m not willing to pay collector prices.
I also seem to recall that there were also monster stickers mixed in – Frankenstein’s Monster, the Werewolf. In fact, that’s how I first learned that “Frankenstein” wasn’t actually the monster’s proper name. Who produced those?
Jack Davis, of MAD Magazine fame, was a contributing artist for Wacky Packages.
Looks like Topps produced a collection last year. Here’s the listing on Amazon.
There’s also A book.
I wonder if they make ones which have the same dimensions that real product wrappers do, so you can sneak into your local supermarket and surrepititiously paste them over the real thing…
