 De Montebello also worked to acquire a number of individual masterpieces over the years, including works by Vermeer, Rubens, Guercino, and Nikolaus Gerhaert von Leyden.Among the most celebrated of these acquisitions have been the 11th-century gilt-bronze Cambodian deified king known as the "Golden Boy" in 1988; Vincent Van Gogh's "Wheat Field with Cypresses" in 1993, Jasper Johns' "White Flag" in 1998, and in 2004 the Madonna and Child by the Renaissance master Duccio di Buoninsegna.Throughout this period, the Met under de Montebello's leadership mounted some 30 special exhibitions annually, involving not only all the museum's 17 curatorial departments, but also presenting works of art on loan from public and private collections around the world (current shows listed on the museum's website, metmuseum.org).
