Ed Emberley's smart and simple Animal Drawing Book (1970) was a disarmingly contemporary example of the popular if not quite respectable add-a-line drawing lesson. There are not only more animals here but all sorts of cars, trucks, planes, boats, wagons, furniture, buildings, people, and "this and that." The crowding of each page with ten to 30 items and up to nine steps in the construction of each item makes the book less attractive than its predecessor, but the great variety of objects may be just what devotees of the animal book have been waiting for. Emberley invites junior cartoonists to take off on their own from the basics he supplies, and he makes it seem so easy and enjoyable that they're bound to go on to more creative doodling.
