Herman Wallace had a terrible life: imprisoned for 44 years for a crime he didn’t commit, 41 of which were spent in solitary confinement because of his Black Panther affiliations. In 2013 Wallace’s conviction was overturned and he was finally released, dying of liver cancer just three days later. For the last decade or so of his life, Wallace corresponded with artist-activist Jackie Sumell, who probed Wallace to find out what his dream home might look like. Sumell’s moving, sensitive exhibition features correspondence, a model-size vision of Wallace’s dream house, and a life-size reproduction of his 6 by 9 cell, with areas marked off for the bed, a chair, and one of those toilet-sink combos that was so stupidly in the news last week. The atrium gallery downstairs features a library of books from Wallace’s reading list.
