I first noticed Diana Walker's artistic portraits when I was a child, and a big fan of Ronald Reagan (I know, I know). Whenever I would see a picture of President Reagan that I thought told a story from a unique perspective, it was usually one of Diana Walker's photographs. “The Bigger Picture” is a montage of her images that includes the Carters, the Reagans, the Bushs, and the Clintons. She claims that only one person has every treated her rudely (George W Bush on the campaign trail) and that Clinton seemed to forget that she was even there (I think he knew she was there, but made it seem like he didn't). If you love political photography like I do, then you might enjoy this collection.
