Seiberling Latex Products Co. A Disney licensee from 1934 to 1942, they made rubber figures of various characters. Their Mickey Mouse figures are fairly common, as are those of the Seven Dwarfs. However, Snow White herself from the latter set is almost impossible to find. She was made of hollow rubber; the Dwarfs were solid. While the Dwarfs have survived, it is sad to see the few remaining Snow Whites, which have in most cases collapsed into themselves from age.
