Reading may be an overstatement. I have read all of the test and looked through all the pages; I haven't started drawing. There is not a lot of text, but the point is the breakdown of different cartoon characters.
A lot of the benefit of this approach is going to be working with proportions, and getting used to how the size of the heads and bodies and features should relate to each other. There is a wide variety of figures, but they are a little dated (original copyright 1979), so it may not have a strong appeal for young aspiring artists. I think there is still value, because the method is still useful, and with the different styles, there is still some variety where you get an idea of how many different types and styles are possible.
This was a really interesting interesting book. While I wish that more cartoon characters had been included in the book, it was still very informative.
One only bought these if you did purchasing for a school district, otherwise they weren't in bookstores at the time. I checked them out so often that the school librarian purchased them for my mother to give me for birthdays and Christmas. They're hardcover classics.
