This book took me forever to read! And I enjoyed it but it’s a slightly dry and academic look of the lives of the four cartoonists whose names are in the title. I grew up often reading the New Yorker cartoons and I enjoyed getting a slightly wonk-y look at what made some of the more well known cartoonists tick, where they came from, what their personal lives were like, etc. It was super dry, however, and did not have as many cartoons in it as I might have wanted. Learned stuff, enjoyed it, had a hard time getting through it.
