A Métascope multi-view table stereoscope for viewing 45x107mm glass stereoviews by Unis France, one of the trademarks of Mattey from Paris.
A rare wooden box with a hundred 45x107 glass stereoviews with images of the First World War and a basic handheld stereoscope.
Last month I've acquired my second table stereoscope. It's a beautiful late 19th century deluxe rotary viewer, built by the French manufacturer Mattey. This multiple-view device supports paper and glass stereo views in both 45x107 and 6x13 formats.
