For two weeks in 2018, internationally acclaimed artist JR brought his mobile photo studio to San Francisco and set out to create a portrait of the city in over 1,000 people. The individual portraits will combine to form a vast photographic mural to be installed at SFMOMA in early 2019. This book tells the story of the project and the story of the city. It features over 1,000 individual portraits, selected first-person accounts from participants, behind-the-scenes photos, a forward by JR, essays by artworld and San Francisco luminaries, and a removable poster of the mural, tucked in a pocket on the inside front cover.
