Throughout his forty-year plus career, Kabakov has produced a wide range of paintings, drawings, installations, and theoretical texts—not to mention extensive memoirs that track his life from his childhood to the early 1980s. In recent years, he has created installations that evoked the visual culture of the Soviet Union, though this theme has never been the exclusive focus of his work. Unlike some underground Soviet artists, Kabakov joined the Union of Soviet Artists in 1959, and became a full member in 1962. This was a prestigious position in the USSR and it brought with it substantial material benefits. In general, Kabakov illustrated children's books for 3–6 months each year and then spent the remainder of his time on his own projects.
