Did you know that many libraries have 3D images that are over 100 years old? These images are called stereographs. The Library of Congress explains that “stereographs consist of two nearly identical photographs or photomechanical prints, paired to produce the illusion of a single three-dimensional image, usually when viewed through a stereoscope.”
Browse over 8,000 stereographs from the Library of Congress.
Or use the New York Public Library’s Stereogranimator to make your own animated gifs from stereographs.
