Tokyo on Foot is the most amazing book I've seen in a long time. This book is by Florent Chavouet, a wonderful artist that while living in Tokyo for 6 months documented everything he saw and did in his sketchbook. The book is full of beautiful and comical color pencil renderings, of buildings, people, parks, maps, plus the notes and bits of story are really funny. Here are a few pages.
