"Signaal" was a skillfully compiled and richly illustrated biweekly war account with exciting battle stories and enticing color photographs. Yet, Signaal is more than just an exceptionally well-made magazine. With its twenty translated issues and a total circulation of over 2.5 million copies, Signaal was the most widely read magazine in Europe during World War II. Ultimately, 111 issues of Signaal were published. The first issue appeared in April 1940 and the last in March 1945. It was published in various languages and distributed in Norway, Sweden, Denmark, the Netherlands, Belgium, France, Spain, Portugal, Poland, Russia, Hungary, Croatia, Romania, Bulgaria, and even a reduced English version, which was flown over the Channel by the V-weapon. Until December 1941, the English edition was also available in the USA. It was through this prestigious magazine that a large part of the territories occupied by Nazi Germany first came into contact with National Socialism.
