During an anti–Vietnam War demonstration in October 1967, a young protester stepped forward and held a chrysanthemum toward a line of soldiers armed with bayonets. Her quiet act set a stark contrast against the armed military police, creating a moment of stillness amid a charged confrontation. Marc Riboud photographed the exchange, and the resulting image became emblematic of non-violent resistance, using the simplicity of a flower to challenge the presence of weapons and the ongoing war.
