“I have long been an admirer of this ubiquitous symbol; it is a fine piece of public information design and it meets the necessary criteria for being an effective icon. It is distinctive, evocative, simple, easy to use, legible, and memorable. I would like to give credit to its creator but I have been unable to discover who designed it.”
— John Lloyd
