Wacky Packages were sold as T-Shirt transfers called "Put-Ons".
They come attached to wax paper, but it is rare to find them in their original plastic bag with the "Put-Ons" header.
They came out in 1973/1974 and carried the Topps copyright.
Known titles are Ajerx, Camals, Grave Train, Fang, Hawaiian Punks, Jail-O, & Minute Lice.
Another set was printed without the copyright and it included Duzn't and Vile. It's not known if this second set was licensed or not, and they don't demand the same prices as the first set.
A Beastball Iron-on was given away in newspapers in 1982.
Topps also put out a set in 1975 called 'Far-Out Iron-Ons". Most were groovy 70's designs, but one was a wacky-like parody of Camel Cigarettes called "Who's a Chicken".
