What a beautiful profession. Complex subjects are summarized in one picture. And also a fascinating interplay between the intention of a designer, the acceptance of the client and the projection of the user. Strong logos become public property and almost nobody realizes that they were ever made by anyone. Everyone knows the peace sign, but nobody knows Gerald Holtom. He was looking for a universal symbol in 1958 for a protest march against the nuclear bomb. He combined two semaphore signals to spell out "Nuclear Disarmament," and that symbol became the general peace sign for the world. Timeless, iconic and can be used by everyone.
