John Nash (1893-1977) was a quintessential twentieth-century painter of the English countryside, but his remarkable achievements have been overshadowed by the more public persona of his older brother Paul. And yet, when we want to summon up an image of an idyllic summer's day, it is John's 1919 painting 'The Cornfield' that we remember, not one of Paul's. With this book, art critic Andrew Lambirth presents a full-length monograph to address all aspects of John Nash's illustrious creative life.
