Framed Print of Anti-aircraft device, First World War, 1914-1918, (c1920). Creator: Unknown
Anti-aircraft device, First World War, 1914-1918, (c1920). The War against German Aircraft: a Listening Post in the French anti-aircraft Section. These listening posts in the French army consist of four huge horns, which gather up the slightest sound and magnify it by means of a microphone, so that it is impossible for an enemy or other aviator to approach unheard. The horns may be described as reverse megaphones. From The Great World War - A History Volume IV, edited by Frank A Mumby. [The Gresham Publishing Company Ltd, London, c1920].
