Ken Gonzales-Day on challenging ideas about who and what murals are for

Ken Gonzales-Day spent two years driving around Los Angeles, documenting hand-painted signs, street art, graffiti and murals. The images tell us a lot about history, race, and identity in LA. The photos are on view at the Skirball Museum as part of Pacific Standard Time: LA/LA, a collection of exhibits and performances celebrating Latin American and Latino art in Southern California. The show is called Surface Tension.
