Justin Bieber graffiti is part of a widespread and illegal "guerrilla marketing' campaign in San Francsico to promote the Nov. 13 release of the pop star's new album, "Purpose." This example -- photographed on Dec. 26 at 1083 Howard Street -- persists several weeks and multiple rainstorms after it was first applied, much to the irritation of City residents and officials.
