Wacky Packages are stickers (peel and punch-out) that were released by the Topps Chewing Gum company (and their Canadian partner OPC) from 1967 to the most recent series in 2004.
They parody common household products and were extremely popular among children in the 1970’s.
They were funny and clever. Back in the day the humor would have been controversial, but today it all seems quite innocent. These trading cards have a bit of charm that is all their own and are making a come back.
The creation of such little wacky parodies from the 60’s and 70’s is an art form in itself. Artists would be hell bent to create such art today without a ton of legal red tape and court dates.
