This critically-acclaimed mystery-meets-biography shuttles from New York to France to Chicago in search of the late Vivian Maier, a career nanny whose previously unknown cache of 100,000 photographs has earned her a posthumous reputation as one of America’s most accomplished street photographers—and also an early master of the selfie. Using a treasure-trove of recently unearthed photos found in a garage sale, Finding Vivian Maier pieces together Maier’s life story, enigmatic personality and troubled past in an intriguing study of one of the great undiscovered talents of the 20th century.
