This stereoview shows a group of German prisoners of war guarded by French soldiers on horses. They're walking past a house with the text Gott strafe England! 1914/15. The photo was taken in the village of Bucy-le-Long in Northern France.
The vast majority of images from the First World War are black and white photos, but original images in color exist. They were made by using the autochrome process developed by the French Lumière brothers.
My collection contains a Planox Stéréoscope Magnétique table stereoscope for viewing 6x13 glass stereoviews. Special about this stereoscope is that it uses a magnetic pickup mechanism to load the 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.
