exchange of capital: financial capital on the part of the sponsors and symbolic capital on the part of the sponsored". Using this concept from the work of Pierre Bourdieu, Haacke has underlined the idea that corporate sponsorship of art enhances the sponsoring corporations' public reputation, which is of material use to them. Haacke believes, moreover, that both parties are aware of this exchange, and as an artist, Haacke is intent on making this relationship clear to viewers. In 1970, Hans Haacke proposed a work for the exhibition entitled Information to be held at the Museum of Modern Art in New York (an exhibition meant to be an overview of current younger artists), according to which the visitors would be asked to vote on a current socio-political issue. The proposal was accepted, and Haacke prepared his installation, entitled MoMA Poll, but did not hand in the specific question until right before the opening of the show. His query asked, "Would the fact that Governor Rockefeller has not denounced President Nixon's Indochina Policy be a reason for your not voting for him in November?" Visitors were asked to deposit their answers in the appropriate one of two transparent Plexiglas ballot boxes. At the end of the exhibition, there were approximately twice as many Yes ballots as No ballots. Haacke's question commented directly on the involvements of a major donor and board member at MOMA, Nelson Rockefeller. This installation is an early example of what in the art world came to be known as institutional critique. MoMA Poll was cited in 2019 by The New York Times as one of the works of art that defined the contemporary age. In one of his best-known works, which quickly became an art historical landmark, Shapolsky et al. Manhattan Real Estate Holdings, A Real Time Social System, as of May 1, 1971, Haacke took on the real-estate holdings of one of New York City's biggest slum landlords. The work exposed, through meticulous documentation and photographs, the questionable transactions of Harry Shapolsky's real-estate business between 1951 and 1971. Haacke's solo show at the Solomon R. Guggenheim Museum, which was to include this work and which made an issue of the business and personal connections of the museum's trustees, was cancelled on the grounds of artistic impropriety by the museum's director six weeks before the opening. (Shapolsky was not such a trustee, although some have misunderstood the affair
