Scope and content
This item is a handheld metal and wood Holmes style stereoscope. The metal viewer has engravings of flower and leaf details with red fabric lining the metal eyepiece. Slide holder is adjustable and handle folds back onto the viewer. "Mercury Stereoscope Trade Mark" is branded on top of the viewer. 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.
Written on object : Underwood & Underwood New York Pat'd July 28'02 & May 01'06.
