What is it about? It’s about putting a sketchbook in your pocket, going places, whether it is the journey of a lifetime or to the dentist, and then getting the sketchbook out and drawing in it. (Or maybe not a sketchbook, but a smartphone or tablet, because the book includes a section on this, too.) Drawings by around 60 of my favourite international artists shed light on how they go about things, whether the drawings are small, large, in colour, of architecture, parks, people, in cafes, trains or waiting rooms, in war zones and political demonstrations, or in the middle of the night. It has around 300 images in it. That’s what it’s about.
