Stereograph Cards
According to the Library of Congress, “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. Typically, the images are on card mounts, but they may take the form of daguerreotypes, glass negatives, or other processes. Stereographs were first made in the 1850s and are still made today. They were most popular between 1870 and 1920.” Some have explanatory backs (shown), others are blank.
