Was a part of Haacke’s solo show at the Guggenheim and takes on the real-estate holdings of one of New York City’s biggest slum landlords, who was connected to Solomon R. Guggenheim. The work exposed, through meticulous documentation and photographs, the questionable transactions of Harry Shapolsky’s real-estate business between 1951 and 1971. His show was cancelled on the grounds of artistic impropriety by the museum’s director six weeks before the opening.
