A separate Snow White Sculptured Soap figure was also produced. Measures about 5.5" high x 2" wide. The copyright stamp on back of box reads © WALT DISNEY PRODUCTIONS, but no date is given. The Mickey, Donald and Goofy artwork is identical to that on above dwarf soap box.
Inside was a flier instructing interested parties to send $1.00 and a self-addressed stamped envelope with 15¢ postage to Rickert to receive six vinyl Disney stickies. Assuming these vinyl stickies and envelop weigh an ounce or less, the 15¢ first class postage would date this promotion to the late seventies.
