There is certainly enough content here to justify a book on the subject, but the fact that the examples always come back to the author's own sketches (when other examples from art and advertising might have better illustrated the points being made) drags the book away from achieving its goals. Of course, this is also described (again from the dust jacket) as "part autobiography, part artists' portfolio", so I guess the "see how clever I am" (also carried into the text, with stories of "pranks" by the author, such as arranging for his daughter to publish a paper on a subject that he had previously published, partnered with a researcher having the same last name as his co-publisher, so that there would be two papers on the same subject by the same last-name researchers, just a few decades apart ... ensuring, no doubt, that hilarity would ensue) theme is actually more the point than the putative subject itself.

Oh, and for those of you keeping track of my "review backlog", this is the last of the books finished up on the road trip, and I got done with this one in the five hour delay we endured sitting on some distant patch of tarmac at the Indianapolis airport waiting to find some way to return to (tornado-harried) Chicago last Thursday (8/23).
