The "photograffeur" — that's a combination of photographer and graffiti artist — prints humongous versions of the portraits he takes, often in black and white, and "flyposts" them where he chooses. The exhibits span whole cities and continents. JR, who has received a TED Prize for his work, sees the streets as his stage and says he "owns the biggest art gallery in the world."
