SCIENTIFIC TOY AIDS ADVERTISING STUNT (Jul, 1931)
SCIENTIFIC TOY AIDS ADVERTISING STUNT
A plaything of high school science classes, the “Newton color disk,” inspired a Beaumont, Texas, man to invent a new advertising device. Thousands of color combinations appear and vanish on a whirling, motor-driven disk, across which moves an endless belt spotted with colors. At intervals an advertisement, a package of cigarettes, a picture of a girl, or words appears in a hole at the disk’s center.
