This item is a handheld stereoscope made of wood and brass. This object was used to view two nearly identical photographs, or stereographs, as one three dimensional image. The stereograph would be placed in the card holder, next binocular like lenses can be twisted until adjusted to the user's vision. This merges the two images to mimic a three-dimensional effect. A hood on the top of viewer is designed to allow light to illuminate stereograph. Object comes with one glass plate stereograph of Windsor Castle, England.
