New York is a city that belongs to no one, yet to everyone. A canvas open to dreamers, exiles, and those who still believe in the power of anonymity and metamorphosis. This is the New York that JR has captured, the eternal outsider whose art reveals the collective soul of a city often perceived as a concrete monster, but which pulses above all with its invisible beings. Through his monumental collages, JR gives a voice to those we no longer see: the Azerbaijani student lost in the crowd, the forgotten faces of Ellis Island, the ballerina suspended above a Tribeca parking lot. His work transcends public space to create a gallery without walls, where every passerby becomes both spectator and work. This book is a journey through the artist's most emblematic collages. As the preface rightly writes, this city is a magnetic chaos, where he captures the fleeting brilliance of ordinary lives to turn them into ephemeral monuments. Welcome to the artist's New York.
