Gas Mask Training in Stereoscope
A stereoscope (two individual images viewed by left and right eyes producing a 3D image, here combined into a .gif) of a squad of US soldiers learning one by one how to wear their gas masks circa 1918. Note each man has his British-style Brodie helmet at his feet and a Colt-Browning M1911 pistol as his sidearm. The M1911 proved extremely popular with US troops in the trenches and were much sort after by men who would be going on night patrols, which often resulted in close quarter combat, the .45 ACP round proved very effective in these situations.
