In the early to mid - 1930's, Disney with the help of a merchandising executive Herman “Kay” Kamen offered an item called Mickey Mouse Cones, which were paper bills used in exchange for ice cream. This was at a time when they were looking for ways to promote the Disney brand. Several years later bills that resembled dollar bills were produced by Southern Dairies, another Disney licensee. They were produced in red, blue, orange and green and came in denominations of 1, 5, and 10.
