Sketchbooks? I've got loads of them, about 130 or so at the last count. Clients? Loads of them too, but I won't bore you with a lengthy client list: you've got Google for that, and it will tell you that my work has been as diverse as the poster for Wimbledon 2000 & 'Understanding your bowels'! (I'd forgotten THAT). What is a fact, though, is that I'm a much better illustrator now than ever.
