Peace Symbol Icon - Universal Sign of Harmony and Nonviolence #2187996 (License: Personal Use)

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