Still wrote a will in 1978 that left a portion of his work, along with his archives, to his wife Patricia and stated: "I give and bequeath all the remaining works of art executed by me in my collection to an American city that will agree to build or assign and maintain permanent quarters exclusively for these works of art and assure their physical survival with the explicit requirement that none of these works of art will be sold, given, or exchanged but are to be retained in the place described above exclusively assigned to them in perpetuity for exhibition and study." After Still's death in 1980, the Still collection of approximately 2,400 works was sealed off completely from public and scholarly access for more than twenty years.
