The Nelson-Atkins Museum of Art in Kansas City is taking the first step in what it hopes to be a major expansion project. The institution, which currently exhibits about six-percent of its permanent collection, is working to convince donors, members, and the public, that the creation of a larger facility is imperative to the Nelson-Atkins’ ongoing success. The museum, which is home to works by Willem de Kooning, John Singer Sargent, and Thomas Cole, is also lacking in office and storage space.
