Blast! Wyndham Lewis at the NPG

After a rather jejeune display of the annual BP Portrait Award at the National Portrait Gallery (very conventional, almost photographic realism has made a massive comeback in this annual exhibition) it was a delightful shock to step into the new Wyndham Lewis Portraits exhibition at the opposite end of the corridor. Many of these are familiar, not least as Penguin and other bookjackets, but they really do confirm Lewis's mastery of draughtsmanship. Modernist greats like Eliot, Pound and Joyce are here and, er, Edith Sitwell and there is a magical drawing of Rebecca West I hadn't seen before. Lewis lived at an extraordinarily exciting epoch of artistic vigour and newness. His aesthetic battles seem like real ones where ours are with triviality, crass marketing and the invasion of the arts by celebrity culture. It's a tiny exhibition for a fiver but still unmissable. It's on until 19th October
