Colorforms are paper-thin, die-cut vinyl sheet images meant to be applied to plastic laminate in the same manner one would apply paper dolls to a backboard. Vintage Colorforms are considered those made shortly after the founding of the Colorforms company in 1951.
The Colorforms company was started by Harry and Patricia Kislevitz, and the die-cuts were marketed as learning toys for children 3 and under. The first Colorforms were basic numbers, letters and shapes, all made in bright, primary colors. Other early Colorforms were Miss Weather, a doll that came with clothes children could change, and Popeye, the famous character from the popular cartoon show.
