After 1957, Viktor and Nina lived in Vladimir, Russia. She was formally rehabilitated in 1963 after sending a personal appeal to Nikita Khrushchev, who overturned her conviction, citing "unproven accusations".[1][2] She became a member[citation needed] of the Soviet Union of Artists in 1977 and held several solo exhibitions during the 1970s and 1980s, where her paintings were featured prominently in several buildings and the public library.[1][2] Those who knew Nina and Viktor in their later years were unaware of their experiences in the GULAG. Both of them lived to witness the collapse of the Soviet Union in 1991.[1]
