His work mixes Art and Act, talks about commitment, freedom, identity and limit. After he found a camera in the Paris subway, he did a tour of European Street Art, tracking the people who communicate messages via the walls. In 2006, he achieved Portrait of a generation, portraits of the suburban "thugs" that he posted, in huge formats, in the bourgeois districts of Paris. This illegal project became "official" when the Paris City Hall wrapped its building with JR's photos. In 2007, with Marco, he did Face 2 Face, the biggest illegal photo exhibition ever. JR posted huge portraits of Israelis and Palestinians face to face in eight Palestinian and Israeli cities, and on the both sides of the Security fence / Separation wall. In 2008, he embarked for a long international trip for Women are Heroes, a project in which he underlines the dignity of women who are often the targets of conflicts. JR creates "Pervasive Art" that spreads uninvited on the buildings of the slums around Paris, on the walls in the Middle-East, on the broken bridges in Africa or the favelas in Brazil.
