About 40 images of World War I by the Franco-German front. An impressive documentation of the immense tragedy that claimed the lives of tens of millions of people. The lives of the soldiers at the front is unbelievably documented by images taken from the stereo positive plates printed on cotton paper with carbon pigment ink. The living conditions of those who fought to the limit of human endurance for survival, obeying the laws imposed by the military hierarchy that also came to execute those who was dismissed from his fight duties. Some very crude pictures highlighting poor human remains torn by explosions, rotten horses and men hurled on the trees by the blast of powerful bombs, men who protect themselves from the lethal gas, widely used for the first time on the battlefield. A reflection that arises spontaneously on a topic that has ravaged humanity and that continues to devastate it even today, as yesterday: war!
