Dave Smith (Illustrator)
Dave Smith is an illustrator (or "Professional Doodler" to his friends) and enjoys drawing things that make him, and other people, laugh. He also plays the drums, strums a guitar (pretty badly), and has an unhealthy enthusiasm for elderly German campervans. When colouring-in he never goes over the lines. Well, almost never... He lives and works in Devon, with his two children and a nutty Spaniel.
