Rediscovered Spanish Civil War negatives

Lost since 1939, the Mexican Suitcase contains nearly 4,500 negatives documenting the Spanish Civil War by Robert Capa, Chim (David Seymour), and Gerda Taro.

They now on view in an exhibition at the International Center of Photography. Adeline Sire has the story.
