The digital collection Maueranschläge (Wall ordinances) has been created by the Landesarchiv Baden-Württemberg. After the First World War the German Heeresarchiv (Army Archive) started to collect ordinances posted by the German army and military government, now held at the Hauptstaatsarchiv Stuttgart, series J 151. Some 2,500 of the 2,700 digitized ordinances stem from the First World War. They touch in particular Belgium and France, but also the Habsburg Empire and countries in Eastern Europe such as Poland, Russia and Rumania. For Belgium the ordinances were published in three languages (German-French-Dutch), for France in French and German. Some posterlike ordinances are clearly meant for propaganda aims and are quite colourful. You can browse the digitized images using the Bildexplorer, you can search images freely using the Volltextsuche, or search systematically using the tree structure of the Strukturansicht.
The Landesarchiv Baden-Württemberg organizes exhibitions concerning the First World War with the general theme 1914-1918. Erlebt, erlitten, erinnert [1914-1918. Lived, suffered, remembered] in Karlsruhe, Freiburg, Stuttgart and Sigmaringen.
