This item is a handheld wooden Holmes style stereoscope. The viewer hood is lined with red velvet. Slide holder is adjustable and handle bends back onto 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.
