Ilya Kabakov (born 1933) is an artist of note in two distinctly polar disciplines. While living in the Soviet Union for 30 years, he was a well-known, albeit officially sanctioned, children's book illustrator. He was simultaneously amassing a substantial body of unofficial avant-garde work. Since leaving the Soviet Union in 1988, he has been prolific; he is now considered the foremost post-Stalinist Russian artist. His prime means of artistic expression has been sprawling installations largely based on Soviet-related themes.
