This book gives a great insight into his processes and showcases a plethora of sketches, both personal and presentation. It's nice to see some quality old school work in pen and marker. Alot of the work within is quite wild and he clearly watched tons of cartoons when he was growing up (too many?). It is interesting to see how these ideas develop and are toned down into more logical and feasible solutions. This book is about exploratory sketching above all else, the back end of the sketching phase isn't prominent, but never the less, this is a great addition to any collection.
