When I studied abroad in London, one of the museums I liked best was the The National Portrait Gallery.
This portrait is one of my favorites. It was taken by Phillipe Halsman and depicts the Duke and Dutchess of Windsor. Prince Edward abdicated the throne in order to marry Wallis Simpson, a divorcee, who was not allowed to be Queen.
As a side note, I love Halsman's jump photos and think that the next time you take someone's picture, you should require them to jump.
