It became a major distributor of stereographic images, located in Meadville, Pennsylvania. From 1892 to 1963 Keystone produced and distributed both educational and comic/sentimental stereoviews, and stereoscopes. By 1905 it was the world's largest stereographic company. By 1935 it had photographers around the world and a stock of 2 million stereo negatives. Keystone's Stereo-ophthalmic Department was formed in 1932 to meet the needs of eye specialists, safety and efficiency engineers and psychologists who needed stereoscopic vision tests. In 1963 Department A (stereoviews sold to individual families) and the Education Departments were closed down, but Keystone continued to manufacture eye-training stereographic products as a subsidiary of Mast Development Company. In 1972 Mast closed the Meadville manufacturing site.
