In this striking book, the people who blazoned city walls with slogans share their collages, their experiences, their rage. Who was behind the memorable slogans featured here: "She leaves him, he kills her"? "When I go out I want to be free, not brave"? "César Award for shame"? Combining text and photos, this book retraces the history of a movement–nights of art and altercations with the police and "cleaners", the social geography of collage-work offering a broad panorama of the varied emotions that citydwellers are now used to seeing plastered across public spaces.
