Peter Coad was way ahead of the pack (including the GoF and the amigos) and was by far the best modeler I'd ever seen (he's now retired). This is an old book but still a gem. As well as learning modeling by example, in this book you can also see the roots of the four class categories that later became the four color archetypes.
