In the everyday bustle of San Francisco life, it can be easy to miss the colorful street art that covers the City's structures. Tucked away off the main drag or raised above street level, these murals breathe life into a concrete city, and sometimes, they do seem to be alive. Faces laugh, animals lurk, and cartoons giggle. All it takes is looking up or walking around the block to discover a masterpiece. Here are some of the best in SF.
