I found a catalog from 1918 by Photo-Plait from Paris. This photography store sold stereoviews of the First World War. To my surprise, the numbers in the catalogue correspond to the numbers on the slides of La Stéréoscopie Universelle. It establishes the link between producer and seller.
I've extended my collection with an interesting set of 50 glass 45x107 stereoviews and a simple stereoscope. The stereoviews are published by the Service des Ventes de l'U.N.C. (SDV).
The Glyphoscope was a stereo camera using glass plates, developed by the famous manufacturer Jules Richard from Paris. It was a compact, simple and affordable camera that could also serve as a stereoscope.
When searching for stereoviews to extend my collection, I always pay special attention to images of sites I’ve visited while working on my photo projects. I was delighted to found a slide of Fort de Troyon. It brings back good memories of my visit to this fort in 2015.
Last month I've acquired my second cabinet 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 6x30 formats.
The majority of French stereoviews from the First World War are not rare. They were produced in large numbers and are offered on many online auction sites. Much less is known about the photographers, manufacturers and sellers. That's why simple documents can sometimes reveal valuable information.
I’m collecting glass stereoviews since 2018. It started with the purchase of individual slides with images of the Battle of Verdun. My collection started to grow with the acquisition of a lot with 144 stereoviews in 6x13 format. All slides are from the same manufacturer: La Stéréoscopie Universelle, abbreviated LSU.
I've added 23 glass stereoviews to my collection of images from the First World War. This time no trenches, soldiers or destruction. These images show the monuments of Paris, covered by sandbags to protect them against enemy fire.
My latest acquisition is an antique cabinet stereoscope for viewing 45x107 glass stereoviews. The stereoscope dates from the beginning of the 20th century and is built by Hemdé. I wanted to know everything about the device and its maker. A product catalogue and online archives revealed some information about its past.
A new passion was born after I looked for the first time through the lenses of my Zeiss Ikon 628/8 stereoscope. I viewed an image of the Battle of Verdun and the visual experience and 3D effect made a big impression on me.
