To create the piece, The Chronicles of San Francisco, JR set up a mobile studio in 22 locations around the city, where he filmed, photographed, and interviewed more than 1,200 people from across San Francisco’s multifaceted communities. In the completed work, a digital mural scrolls across the enormous LED display, bringing together the faces and untold stories of everyday people.

The digital display contains nearly 26 million pixels, and is likely the highest-resolution LED screen in the U.S.
