Sesame Street Magic Slates

Western Publishing released a series of "Magic Slate Paper Saver" toys featuring Sesame Street characters in the 1970's, 1980's and 1990's. These were originially published under the Whitman brand, and later under Golden Books. Each consists of a piece of stiff cardboard, with a sheet of cellophane over a soft waxy surface on the front. Using the included red plastic "pen", a child can draw on the cellophane, and then lift it to erase and start over.
