Scope and content

The stereograph would be placed in the card holder and adjusted to fit the user's vision until the two images overlap to mimic a three-dimensional effect. Item is metal with a plastic eye piece. A lamp bulb is installed and attached to a power cable. Lamp bulb illuminates backs of stereographs or transparencies when viewed through the eye piece. Patent No. 2557608 made by Keystone View Company. Comes with 4 stereographs made by various photographers and studios such as G.W. Wilson, Underwood & Underwood and B.W Kilburn.
