The symbol is a superposition of the semaphore signals for the letters "N" and "D", taken to stand for "nuclear disarmament", [2] while simultaneously acting as a reference to Goya's The Third of May 1808 (1814) (aka "Peasant Before the Firing Squad"). [3] The V hand signal and the peace flag also became international peace symbols.

The Union Switch & Signal company (US&S) introduced an electro-pneumatic design in ...

But the cross, for these people, had too many wrong associations – with the Crusaders, with military medals, with the public blessing by an American chaplain of the airplane that flew to Hiroshima – and eventually the arms of the cross were depicted as declining, forming the composite semaphore signal for the letters N and D (the letters "N ...
The mechanical signalling system was designed by Siemens & Halske and used semaphores for the main signals and square boards for the distant signals. Most semaphores had one arm, whilst a small number, which were followed by points, had two arms. The line between Piraeus and Omonoia Square was divided into six blocks.
