Silver Peace Sign Ring

Designed by British artist and conscientious objector Gerald Holtom for what then was the Direct Action Committee Against Nuclear War, the bisected circle with two downward spokes combined the semaphores for the letters “N” - two flags held down at a 45 degree angle - and “D,” one up, one down.

The symbol was unveiled Feb. 21, 1958, according to the New York Public Radio show “On the Media,” and made its public debut at a 1958 Easter weekend anti-nuclear march, according to CND.

It later migrated to the U.S., where it was adopted by student pacifists and later by the anti-Vietnam War movement.

Columbia University professor Todd Gitlin said it was in the mid- to late 1970s that the peace sign started to become more of a fashion statement.

As the anti-war activists of the 1960s grew older, a younger generation was looking for a way of declaring who they were, Gitlin said. “For them, it seemed to signify being righteous or hip.”

“Back in the ’60s and ’70s, everyone was familiar with the sign. People were putting it on their graduation caps,” said Keith Knutson, a Viterbo University professor who said he protested the Vietnam War before serving in the Navy.
