Robert Capa, Republican soldiers in destroyed building on lookout for Nationalist soldiers, Teruel, Spain, December 1937

Last year, a suitcase was found in Mexico with some 4,300 frames from the Spanish Civil War. Turns out, the negatives were shot by Robert Capa, his girlfriend Gerda Taro and wartime photographer David (Chim) Seymour.

Naturally, the “Mexican Suitcase” (as it is being called) was turned over to the ICP (a fitting move, given Robert’s brother Cornell founded the institution). The ICP is now hosting an online gallery of the recently (and painstakingly) scanned images.

Fans of Capa’s wartime and photo journalistic work might be disappointed to learn that “The Falling Soldier” wasn’t among the found frames. “The Falling Soldier” depicts a Loyalist militia man falling to the ground after allegedly being shot. Although one of the most famous war photographs of all time, its authenticity is commonly questioned. The ICP asserts it was not a staged shot.
