There was a great documentary on the BBC recently about the American Painter Andrew Wyeth by Michael Palin (he of Monty Python fame). Often disregarded by critics who are all too happy to big up Edward Hopper it explored Wyeth's work and whether it's rural setting and his unwillingness to play the fame game had lead to his under rated appeal. You may be familiar with the painting below "Christina's World"
