It's often said that to understand society, look at its artists. To get an idea of how much this once-quirky city has grown up, look no further than Sirron Norris. The muralist who created the "cartoon literalism" genre once addressed issues of gentrification with paintings like Victorion: El Defensor de la Mission. These days he has his own studio, and commercial projects ranging from cartoons on Fox to paintings commissioned by the InterContinental hotel. "When I started, [my art] was really more urban because the city was like that," Norris says. "But as commercial work came in, I had to tell other people's stories." The themes of his work might have changed, but it looks better than ever. We could say the same thing about San Francisco.
