We are all artists as children, painting and drawing each day. Most of us stop when we get older – but David Gentleman kept going. For over 90 years he has been drawing, painting, engraving and printing, rising to become one of Britain’s best-known and most loved artists. His watercolours have filled galleries; his iconic wood cuts are emblazoned across posters, book jackets and train stations; his stamps have made their way to the furthest corners of the world. Here, the great, polymathic artist and craftsman shares what he has learned over the course of a lifetime of making and thinking about art.
