“I just drew it spontaneously when I heard the news,” Jullien tells Quartz. “I wanted a symbol of peace and solidarity for Paris. It’s a drawing for everybody to use to call for peace and to show solidarity with the victims.”

Jullien, who makes a living drawing clever (sometimes irreverent) visual puns for Nike, The New Yorker, and BMW, also created a widely shared pacifist illustration in reaction to the Charlie Hebdo attacks in January.

Just as the original peace symbol designed by Gerald Herbert Holtom in the late 1950’s served as a “visual plea” for British nuclear disarmament, Jullien’s sketch has become a shorthand for sobriety and calm as the events continued to unfold in the French capital.
