Photojournalism has been a staple of National Geographic for more than a century, and their cover images have made their impression upon the globe since their first release in 1959.

Two National Geographic photographers join The Daily Circuit to talk about "The Covers: Iconic Photographs, Unforgettable Stories," a new book which compiles decades of photographs and their stories.
