'Lady Liberty': The story behind the pictures

Our guest is Luce Lebart, a curator and historian of photography. Her latest show involves a trip across the Atlantic and back in time - a look through the archives at Lady Liberty, the statue which became synonymous with New York. Dreamed up as a symbol of Franco-American friendship, "Liberty Enlightening the World" is now an icon, and much of that is thanks to the photographic medium. Luce Lebart tells us more.
