“John Myatt is an artist. He is not, he is the first to admit, the world’s finest artist. He is, however, quite possibly the world’s finest forger. What he is doing, now, for up to £5,000 a painting, is forging to order, entirely legitimately: his ‘genuine fakes’ are stamped as such on the obverse, and his perfect (if Dulux) versions of, say, Giacometti’s Seated Nude, or Matisse’s The Pink Room, now grace ski lodges in Aspen and villas in Tuscany. It’s all great fun, and above board: it wasn’t always so.”
