From artist's website: " The Market Street Railway mural shows a 180-degree trans-temporal bird's eye view of San Francisco's Market Street, divided vertically into sections corresponding to different decades and historic moments, from the 1920's to the present, and into an imaginary utopian future. The mural celebrates the vital role of public space in our cities, and it contains lots of detailed references to local street art, activism, and various SF subcultures. It is a tribute to the urban center as a place uniquely conducive to collective expression, a place where history is made, and politics become physically felt. It is also an homage to San Francisco in particular, as a place where people have kept inventing new ways of utilizing our shared space to communicate, provoke, and interact, which is what made this a vibrant and engaging place to live."
