Maine's Farnsworth Art Museum has announced a $12 million endowment campaign to sustain the artistic legacy of Andrew Wyeth. The Andrew Wyeth Memorial Endowment campaign will be funded by a Sotheby's auction in New York of museum-quality art works donated by Wyeth family members, artists, collectors and others interested in honoring Wyeth and supporting the museum's mission of celebrating Maine's role in American art. The auction is slated for October 2010.
