In 1919 publishing company Van Cortenberg published photographs from World War One with the title "Never Let Us Forget". Those pictures were sold as postcards for the benefit of widows and orphans. This book collects these photographs together; 365 images at the western front of World War One give the reader a unique view of the battlefield and the daily life in and around the trenches: wounded people, soldiers relaxing, arms, ammunition factories with civilians, guards, cold winters, airplanes, artillery and soldiers marching towards the front. All the featured pictures have a legend in 4 languages; some of them have larger comments and are placed in an historical context.
