When David Burnett saw Scout Tufankjian's picture of President Obama hugging First Lady Michelle Obama that went viral in the hours after Election Day, the image rang a bell. He remembered it was from last August at a rally in Iowa, an event Burnett covered on assignment for People magazine. Checking his images, he found he'd shot the same moment - but from the exact opposite side. Burnett's image shows the First Lady's face and emotions, the flip-side to Tufankjian's picture. Julia Turner writes about what Burnett has to say about that day in an article in Slate here.
