These cards were issued in 1937 by a number of German cigarette companies and were included in packs of cigarettes for collecting by the consumer. Although these cards were created after the war, they are colorized versions of photos taken by the German War Ministry during the war. They show scenes of trench warfare during the First World War. Trenches were characteristic of WWI and new technologies such as trench diggers and portable gas/electric spotlights made this possible. Life in the trenches was hard and many soldiers developed trench diseases, such as trench foot or trench fever.
