French artist JR transforms streets into open-air galleries with his monumental black-and-white photographic collages. Blending art, activism, and community, his global projects--like Inside Out, The Chronicles of New York City, and Ellis Island’s Unframed--turn public spaces into stages for untold stories. Collaborating with locals, he’s pasted portraits on favelas, conflict zones, and even the Louvre. His work crosses into film (Visages, Villages, co-directed with Agnès Varda) and large-scale spectacles (Rio Olympics, Paris’ Pyramid). With a mix of poetry and protest, JR makes art that’s both ephemeral and unforgettable--always asking: Can art change the world?
