Serge Grigoriev (1883–1968), rehearsal director for the Ballets Russes between 1909 and 1929, compiled a series of photograph albums that show the company rehearsing, performing, and relaxing. This page of snapshots, taken by Grigoriev in Monte Carlo in 1928, includes Diaghilev and his artistic collaborator Boris Kochno (1904–1990); the artist Pablo Picasso (1881–1973) and his son Paulo (1921–1975), and Picasso’s first wife, the dancer Olga Khokhlova (1891–1955).
