In 1915, Chagall began exhibiting his work in Moscow, first exhibiting his works at a well-known salon and in 1916 exhibiting pictures in St. Petersburg. He again showed his art at a Moscow exhibition of avant-garde artists. This exposure brought recognition, and a number of wealthy collectors began buying his art. He also began illustrating a number of Yiddish books with ink drawings. He illustrated I. L. Peretz's "The Magician" in 1917. Chagall was 30 years old and had begun to become well known.
