Corrective Calisthenics Stereoview c1930 Keystone Stereoscopic Treatment A1225: $17.97
\"Right Hyper-exophoria Corrective Calisthenics (RHX)\"
Published by Keystone View Company, formerly one of the largest stereoview publishers in the world.
This is a stereoview (also known as a stereograph or stereoscope card). It was one of the first forms of 3D photography. The images were captured with a special stereoscopic camera, which had two lenses - simulating the view of our left and right eyes. The two, nearly identical pictures were then mounted next to each other (most commonly on a piece of cardstock, glued on as photographs or printed as lithographs). The image could then be seen in three dimensions when viewed through a device known as a stereoscope, stereopticon, and/or televiewer.
Standard-size stereograph, measuring about 3.5 x 7 inches.
Will be shipped safely and securely! All of my paper items are protected in archival-safe polypropylene sleeves and packaged in rigged cardboard.
