My photo project about the First World War started in Verdun in 2009. Nine years later I started collecting stereoviews of the war. This created a nice interaction between these two passions. I’m now searching for stereoviews with images of locations that I've photographed during my photo project, but I also started taking new photos of locations that I recognised from stereoviews.

The First World War was the first major conflict where photography played an important role. Germany recognised its potential and used photographs for propaganda from 1914. The images were used to influence the public opinion in neutral countries. France realized that it could not stay behind and decided to set up its own photography unit to oppose German propaganda.

Most French stereoviews with images of the First World War contain a short description which is printed on the slide. In best case, it describes the place, subject and a year. However, most descriptions are brief and sometimes even incorrect. This makes it difficult to find out more about the story behind the image.

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).

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.
