Emma Stone - British Vogue, August '12.

Emma Stone's latest magazine cover amidst her flurry of 'The Amazing Spider-Man' press, is the August issue of British 'Vogue'.

The cover was photographed by Mario Testino, and I must say that I infinitely prefer it to Emma's July cover for U.S. 'Vogue' magazine.
