"JR is an anonymous photographer and artist and the 2011 TED Prize winner. In his work, JR embeds into neighborhoods, favelas and villages around the world, photographing the people who live there and learning their stories — and then pasting his striking images onto massive local canvases: buildings, buses, roads and bridges. His latest global art project is called “Women Are Heroes.”
