Door #23 -- June 13, 2012

The door of the Kohler and Chase Building at 26 O'Farrell.  Kohler and Chase was a pioneering music business, founded in San Francisco in 1850.  The building once held their store and their piano factory.

Matt Cain just threw the first perfect game in Giants franchise history.  The Giants also managed to score 10 runs against the Houston Astros.
