For writer Julio Llamazares, photographs by Centelles are “the most powerful of the Spanish Civil War. By their own right, they are a part of our twentieth-century history and will remain as a testimony to a bloody conflict.” Centelles participated actively in the Spanish Civil War, accompanying the Republican army in Aragon and Catalonia. This book contains 59 images taken between 1934 and 1939, a profound vision of the war, its cruelty, desolation and desires for change. He is one of the most committed Spanish photographers as shown by his life and work. He was excluded by Franco’s regime and recently recovered for memory.
