This post has been updated with a statement from the artist.
As the brutal attacks rocked Paris last night and left 150 dead, people around the world following the events from afar searched for a way to show their solidarity with the people of the beloved French capital.
Many flooded social media channels with photos of iconic Parisian landmarks, but a simple, shaky sketch posted by London-based French graphic designer Jean Jullien has become the most notable avatar for the unspeakable tragedy. Captioned “Peace for Paris,” the symbol, comprised of the Eiffel Tower combined with the international symbol for peace been shared over 100,000 times on Instagram.
“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.
