The Wizard of Oz Waddle Book is a novelty edition of The Wonderful Wizard of Oz, and a major example of Oz promotional merchandise.
The book included cardboard cutouts of six characters (Dorothy Gale, Toto, the Scarecrow, the Tin Woodman, the Cowardly Lion, and the Wizard of Oz) which could be detached and assembled into three dimensional dolls using the included instructions. These were designed to walk, or waddle, down a slanted surface. A cardboard Yellow Brick Road was provided for them to waddle on.
Intact copies of the original edition are a very rare Oz collectible, since few have survived. The publisher Applewood Books issued a reprint edition in 1993.
