Colorforms, invented by Harry Kislevitz, are toys produced by the Colorforms Corporation. Colorforms are paper-thin, die-cut vinyl sheet images and shapes that can be applied to a slick cardboard background board, much like placing paper-dolls against a paper backdrop. The images stick to the background via static cling and can be repositioned to create new scenes. The original box sets began appearing in the 1950s and feature bright shapes and "modern" basic designs, expanding into cartoon character sets. Later Colorforms licensed various properties, produceing box sets supporting various TV series and movie releases.
The Colorforms Corporation also produces Shrinky Dinks, the Colorform Aliens Outer Space Men, Dress-Up Sets and Print Putty.
The first kits were manufactured by the major toy companies of the time such as Milton Bradley, Colorforms, Western Publishing, Skyline Toys and other companies.
The shrink plastic is still available from many retailers and can be used for anything from charms to pins.
