This collection consists of topical sets of educational stereographs intended as visual aids for instruction for elementary
school children. Though most topics relate to the natural sciences, two boxes relate to a Reading curriculum based around
domestic activities and the life of a child. Each of the 16 boxes contains 25 stereographs.
The Keystone View Company, located in Meadville, Pennsylvania, was founded in 1892 and was the major producer of stereographic
images in America until 1972 when it closed. In 1905, Keystone began producing stereographs and lantern slides to aid instruction
in its Educational Department, which sold to schools, churches, and civic organizations. The Educational Department produced
stereographs for teaching geography, reading, science, history, social sciences, and topics in health and medicine. A selected
compilation of these educational sets were marketed as the "Keystone 600 Set." A teacher's guide to this set was published
under the title, Visual Education.
