Signal was an illustrated photo journal and army propaganda tool,[1] meant specifically for audiences in neutral, allied, and occupied countries.

The journal was published by Ullstein Verlag and characterized by an outstanding print quality for the time.

Each issue contained several (mostly eight) color pages, which was very unusual at the time.

The promoter of the magazine was the chief of the Wehrmacht Propaganda Troops, Colonel Hasso von Wedel.

Signal was published fortnightly (plus some special issues) in as many as 25 editions and 30 languages, and at its height had a circulation of 2,500,000 copies.
