Thanks for posting this, Amid–I got a taste of Ketcham’s early magazine cartoons years ago, from his bio “The Merchant of Dennis The Menace.” What I found the most interesting is that there’s a “proto-Dennis” in a lot of those early cartoons. Speaking of which, does the book include samples of the comic strip Ketcham failed to sell, “Little Joe?” That character was also very Dennis-like in appearance and manner.

This sounds like the sort of book I’d love to have if I can ever afford it.

I can imagine what the caption is on the cover:

Mother: “Don’t worry…I have every intention of heading him off at the pass!”.
