The Royal Academy’s ‘America After the Fall: Painting in the 1930s’ (25 February–4 June) will also concentrate on works by figurative artists of the period – among them Charles Sheeler, Thomas Hart Benton, and Edward Hopper – and include that great icon, American Gothic by Grant Wood. Wood’s uncompromising depiction of an austere Midwest farmer and his wife (posed for by his sister and his dentist) in front of their gothic wooden homestead, evokes the harshness of life in the American heartland during the Depression years, in the way that no non-figurative work could ever do. It justly deserves its status, and is among that small band of works that have penetrated so deeply into the public consciousness that they can be appropriated by cartoonists and others without further reference.
