Any map of the subject must be rooted in the description of the Land of Oz given by L. Frank Baum in the first Oz book, The Wonderful Wizard of Oz, which details the four separate countries of Oz in the four cardinal directions, with their names and characteristic colors. (The term "Gillikin" is not introduced until the opening chapter of the second Oz book, The Marvelous Land of Oz.) The earliest known map of Oz is one that Baum had made for his Fairylogue and Radio-Plays in 1908. It shows the four countries with their proper colors, located in their proper places — Gillikins up, Quadlings down, Munchkins to the East on the right, Winkies to the West on the left.
