Accomplished in many phases of cartooning, the prolific Gerberg shares the tricks of his trade in this updated and expanded edition of his Arbor House Book of Cartooning ( LJ 11/15/83). Part 1 is devoted to the familiar magazine or ``gag'' cartoon, seemingly his first love and a good base for discussion of other cartoon forms. Part 2 covers other earning opportunities, including comic strips, editorial cartoons, spot illustrations, animation, advertising, TV, comic books, greeting cards, and humor books. That he is at home in all these areas is evident in his anecdotes, advice, and art work and in his choice of work by other big names. Not an elaborate ``how to draw'' manual; the book's strength is in its historical background and wide-ranging lowdown on materials, marketing, and making contacts--in short, on how things are done by the pros.-- William A. Donovan, Chicago P.L.
