Children’s Book Review: Three Lines in a Circle (2021)

Three Lines in a Circle: The Exciting Life of the Peace Symbol by Michael G. Long

[Gerald Holtom] explained that when drawing the symbol, he adopted letters from semaphore, the alphabet used by people sending messages by flags. The two lines pointing downward and to the sides came from the semaphore letter for N, and the center line represented the letter D. Placed on top of each other and enclosed in a circle, the three lines stood for “nuclear disarmament.”

I really loved this little...
