With the revival of animation in Hollywood, this latest of Sennett's books on movies is timely. Idea man William Hanna and artist Joseph Barbera created Tom and Jerry at MGM, then through revolutionary limited TV animation built today's thriving ``General Motors of animation,'' home of the Flintstones and so many others. Reading like an official company history, full of praise for the men and their creations, this is informative, upbeat, and impressive, with deep colors on heavy paper. The simple Hanna-Barbera art is a bit spare for these giant glossy pages, compared with the delicate detail in Christopher Finch's The Art of Walt Disney (1973). But having between two covers all the Hanna-Barbera characters, series, features, and lore is a welcome event. Recommended for art, media studies, and popular collections.--William A.
