San Francisco's legendary Mission District boasts a greater concentration of street art than any other neighbourhood in the world. Beginning in the early 1970s as a form of social and political activism, a vibrant public mural movement has flourished in this dynamic, multicultural community. The result is a spectacular, ever-changing urban landscape transformed by the artistic convergence of traditional Mexican mural painting, folk art, Surrealism, Pop art, underground comics, advertising and graffiti. With 900 stunning photographs, this book showcases more than three decades of work by a diverse array of artists, from the conspicuously anonymous to the internationally famous.
