Preston Blair’s Animation (Book 1) is the best “how to” book on cartoon animation ever published. When Blair put the book together in 1947, he used the characters he had animated at Disney and MGM to illustrate the various basic principles of animation. Apparently, the rights to use some of the characters were revoked after the book was already in the stores. Publication was halted for a time, and he was forced to redraw most of the MGM characters, replacing them with generic characters of his own design. The revised edition went on to become a classic, and the first edition was forgotten.
