Peace Symbol Icon - Universal Sign of Harmony and Nonviolence #2187807 (License: Personal Use)

This minimalist black-and-white icon features a circle enclosing three bold lines: a vertical line intersected by two downward-sloping lines, representing the semaphore signals for “N” and “D” (nuclear disarmament). Originally created by Gerald Holtom for the Campaign for Nuclear Disarmament (CND), it rapidly evolved into a universal symbol of peace, adopted by counterculture movements, activists, and global humanitarian efforts.

Used on websites, educational materials, protest graphics, merchandise, and social media to convey messages of pacifism, unity, anti-war sentiment, and hope; ideal for pages about activism, history, symbolism, or global citizenship.
