This week, British writer and photographer David Campany presents this multilayered poster taken from press photos of Andrew Wyeth's painting, titled ‘Christina's World’. “I like the idea that a press photo is a kind of public address but a very different kind of public address to a street poster. Press photos like this are also anachronistic, of course, as they're all shot digitally these days. Plus, it's almost a black and white image, but not.” Go see NOW! @ 2 Hoxton Street, London.
