mid-late 19th century
A stereo-graphoscope (English, mid-late 19th century) made by Negretti & Zambra. Photographs can be viewed in two different ways with this device. The stereo lens allows the viewer to be used as a stereoscope, which creates a 3-D effect with stereograph images. Alternatively, the stereo lenses can be folded back and the graphoscope flipped into place to provide a magnifying lens. The whole upper half can be set at various viewing angles with the jigsaw-cut wooden ratchet underneath or folded to lie flat. The slide holder is adjustable to accommodate various sized photographs. Adhered to the front is a rectangular plaque inscribed “NEGRETTI & ZAMBRA / OPTICIANS TO THE QUEEN / 122 REGENT STREET / LONDON.” Originally from the collection at Green Animals.
