Peace Symbol Icon - Universal Sign for Harmony and Anti-War Movements #2188357 (License: Personal Use)

This minimalist black-and-white icon features a circle enclosing three lines-two forming downward arms and one vertical stem-originally derived from the semaphore signals for "N" and "D" (Nuclear Disarmament). Created by Gerald Holtom in 1958, it quickly transcended its origins to become a global symbol of pacifism, civil rights, and counterculture movements across decades.

Used on protest signs, apparel, websites, and educational materials related to peace advocacy, activism, history, and social justice; ideal for pages about symbolism, 20th-century movements, or humanitarian campaigns.
