Vintage View Finder and Stereographic Library

*Keystone Co. founded in 1892, grew to be the largest, most prominent publisher of stereoscopic photographs in the U.S. By the 1920s Keystone was the only major publisher of stereoscopic photographs in the world and became one of the only publishers permitted to photograph World War I battlefields and military operations. *A stereoscope is a device for viewing a pair of separate images as a single 3-D image which appears larger and more distant. *Stereoscopic slides portray a wide variety of geographic locations. Military activities on the French warfront are most strongly represented. Slides detail troops, city ruins, battlefield ruins, trenches, medical operations, troop provisioning, and post-event recordings of key turning points in the war. *This complete collection contains 50 black&white stereoscopic photographs depicting various World War I scenes between 1918 and 1921 including battlefields, soldiers, and activities on the home front.
