"Hoo-hah!"
Daniel B. Willingham has proven himself many times over as a creative genius. And owning this book is a great way to have quick access to his material rather than having the brave the (sometimes confusing)interface of the website.
Unfortunately, this volume focus's mainly on the newer material in terms of multi-page comics and series. Meaning (in my opinion) some of his very best work doesn't get a look in. I'm hoping for a volume 2 which includes these beauties:
