Photographs taken by Robert Capa, Gerda Taro and David Seymour "Chim" during the Spanish Civil War. Their trail was lost in 1939 and now they are displayed at the Bilbao Museum of Fine Arts.

These extraordinary pictures, many of them unpublished, make up what is known as the "Mexican suitcase", the most important set of recovered film negatives in the 20th century.

The negatives include previously unknown portraits of people such as Federico García Lorca and Ernest Hemingway.
