Item also comes with a two page photocopy of an exert from a book on stereoscopes and other optical instruments originally written on Novemeber 20th 1858 printed by George Edward Erye and William Spotiswood. Stereoscopic viewer is made from wood and metal and lined with gold trimmed red velvet. Stereoscopic viewer is adjustable and comes with a small knob to hold. Stereographs have a range of well known manufacturers like Underwood & Underwood and pirated replicas by unknown producers. The stereoscopic viewer 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.
