| IRS990/Desc | 0 | The Brandywine Museum of Art engages audiences through its presentation and interpretation of American art with a particular focus on the Wyeth family and other artists who lived and worked in the Brandywine Valley region. Since its founding in 1971, the Museum has assembled a collection of over 4,000 objects from the mid-nineteenth century to the present with major holdings of landscape and still-life painting, illustration, and paintings by three generations of the Wyeth family. The Museum has a distinguished program of temporary exhibitions and publications that have made significant contributions to scholarship in the field of American art. In addition to its collection, the Brandywine owns and makes open to the public seasonally three historic properties, all designated National Historic Landmarks, that include the studios of N. C. and Andrew Wyeth. |
