#142.
On 21 February 1958, the peace symbol design was completed. It was commissioned by the British Campaign for Nuclear Disarmament. The three lines inside the circle represent the letters "N" and "D", for Nuclear Disarmament used in a particular system of notation. This system uses flags to send information great distances, such as from one ship to another ship. "N" is formed by a person holding a flag in each hand and pointing it toward the ground at a 45-degree angle. "D" is formed by a person holding one flag straight down and one straight up. What is the name of the system?
