Snow White's Adventures was updated at Disneyland with the 1983 Fantasyland renovation. This "Scary Adventures" poster was created for the new ride. Designed by Leticia Leiever. Measures 24" x 36".
In 1984, a commemorative reproduction of this poster was made available to members of the Disneyland Magic Kingdom Club. See it in an earlier post.
