Antique Irish Stereoview Lot of 8 Kerry Cobh Killarney Lake Dublin Ireland D2100 For Sale

These are stereoviews (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, televiewer and/or realisticscope.

Published by Keystone View Company and others in the late 19th and early 20th century. Standard-size stereographs, measuring about 3.5 x 7 inches.
