PORTLAND; ME (AP).- A Jamie Wyeth portrait of his late father has sold for $2.4 million at an auction to benefit a museum that is devoted to the Maine-related artworks of three generations of Wyeths. The 1969 oil painting, “Portrait of Andrew Wyeth,” was among 12 pieces that sold Nov. 29 at the Adelson Galleries in New York City as part of the Farnsworth Art Museum‘s endowment campaign to sustain the artistic legacy of Andrew Wyeth, David Troup, spokesman for the Rockland museum, said Tuesday. It was a record amount for a Jamie Wyeth painting. The auction raised about $4 million for the campaign. In all, $9 million has been raised toward the $12 million goal. The sale began online Nov. 8, and final bids were made in person and by phone at the Adelson Galleries. The auctioned pieces were donated by artists, collectors and philanthropists with an interest in sustaining the museum’s mission.
