They depicted: 1) a heap of murdered prisoners, naked and sprawling, and already partly decomposed; 2) a huge quantity of piled-up shoes, which had belonged to those or other prisoners; 3) a group of prisoners, still alive, seen behind a metal fence; 4) the “death stairway” of 186 very high and irregular steps, which the forced laborers were made to climb under enormous loads right to the top, from which they were then often flung down into the pit below as a spectacle for the camp authorities; 5) a sentenced man on his knees before the ditch he himself has been made to dig, guarded by numerous German soldiers, one of whom is about to shoot him at the nape of the neck; 6) and a little series of frames (four in all) which show successive stages of a decompression-chamber experiment, performed on a human guinea pig.
