Visitors from Oz: The Wild Adventures of Dorothy, the Scarecrow, and the Tin Woodman is a 1998 Oz novel by Martin Gardner, illustrated by Ted Enik. In his story (which occurs after the action of L. Frank Baum's last Oz book, Glinda of Oz), Gardner employs the type of mathematics puzzle for which he was famous to bring Dorothy Gale, the Scarecrow, and the Tin Woodman to the United States in 1998. Dorothy becomes involved in the manipulations of two movie producers.
