The Association of Art Museum Directors has taken the unusual step of adopting sanctions against Randolph College and its Maier Museum of Art. The group took the action because the college recently sold a masterpiece of American painting, the 1912 work "Men of the Docks," by George Bellows, for $25.5 million in funds for the endowment. Art ethics codes require that museums sell art only to build up collections, not for general financial support for institutions. Under the sanctions, members of the art museum association will stop collaborating with the Maier Museum of Art on exhibitions, either by borrowing or lending work. The News & Advance reported that four museums are expected to cancel plans to borrow works from the Randolph museum. College officials have defended the sale as crucial to the college's long-term financial health.
