Planox is best known for the Planox Stéréoscope Magnétique. However, the company of Alexander Plocq also produced other stereoscopes under the same name, including this basic hand-held viewer. It was designed solely for viewing glass stereoviews. Its most distinctive feature is the supported format of 7 × 15 cm, a size rarely encountered.

A. Plocq
The company Établissements A. Plocq was founded in 1895 by Alexandre Plocq (1871–?), and was located at 26-28 Rue de Center in Paris. His son, Alberic-Alfred Plocq (1896–1974), joined his father’s company and continued Établissements A. Plocq alone in the late 1920s or 1930s. Plocq manufactured hand-held and table-top stereoscopes for 45 x 107 mm, 6 x 13 cm and 7 x 13 cm glass stereoviews.
