Heigh ho! I just love this Wheaties ad from 1955, featuring Disney’s Seven Dwarfs. The large box was just 21 cents. It was a special Disneyland “Light Up” package, which featured full color painted artwork of Walt’s Magic Kingdom on the back of the box! Each box had a perforated hole in the front, and small holes in the back artwork. Consumers were instructed to insert a 7 watt light bulb into the front hole. Then they could watch the lights glisten through the small cutouts in the Disneyland scenes.
