McCurry's famous 'Afghan girl' portrait almost never published

Nearly everyone has seen photographer Steve McCurry’s striking 1985 National Geographic cover portrait of Afghan refugee Sharbat Gula, but it was nearly left on the cutting room floor. He revels the story behind the picture in his new book, "Untold: The Stories Behind the Photographs." McCurry only took a handful of frames before the young girl got up. Editors at National Geographic came close to picking a different image for their cover, but made a change at the last minute.
