Custodial history

Item is a wooden Holmes style handheld stereoscope with velvet lining around the viewer. The handle folds onto viewer. This object was meant to view stereoscopes as three-dimensional images.This object was used to view two nearly identical photographs, or stereographs, as one three dimensional image. The stereograph would be placed in the sliding card holder and adjusted to fit the user's vision until the two images overlap to mimic a three-dimensional effect. Potentially, this object could have been originally manufactured by H.C. White Co. then retailed by Underwood & Underwood.
