The Farnsworth Art Museum of Rockland has announced several major additions to works included in this month’s three-week auction to benefit the prestigious museum’s Andrew Wyeth Memorial Endowment Campaign. The ongoing online auction of museum quality art works, hosted by Adelson Galleries, will culminate Monday, Nov. 29 with a live auction in support of the campaign.

The works, generously donated by artists, collectors and philanthropists dedicated to sustaining the mission of the Farnsworth, include Jamie Wyeth’s 1969 portrait of his father Andrew Wyeth; Andy Warhol’s 1977 “Self Portrait with Skull”; and an Andrew Wyeth 1984 watercolor, “Helga, From the Back.” Works recently added to the auction’s impressive collection include Kenneth Noland’s “Mysteries: Elate”; a 1950 Ferdinand Leger, “Circus Performers”; and the N.C. Wyeth painting “It Was Such a Warm Little House, There.”

The auction preview takes place both online and live at the Adelson Galleries at 19 East 82nd St. On Monday, Nov. 29, a special evening at Adelson Galleries celebrating the life and artistic legacy of Andrew Wyeth will feature the live portion of the auction with Jay E. Cantor, noted historian of American art as well as the founding president of the Georgia O’Keeffe Museum and the founding head of American Paintings department at Christie’s, serving as guest auctioneer and master of ceremonies.

Online bidding is happening now at adelsongalleries.com and will remain open until 6 p.m. on Nov. 29. The live auction then will take place from 7:30 to 8 p.m. The celebratory event is open to invited guests, and interested parties are invited to visit adelsongalleries.com or farnsworthmuseum.org; or call 212-439-6800 for more information.

First announced in September 2009, the $12 million Andrew Wyeth Memorial Endowment campaign will support the maintenance and operation of four of the Farnsworth Art Museum’s properties: the Olson House in Cushing; and the Wyeth Center, Wyeth Study Center and Wyeth Research Center in Rockland. The Farnsworth Art Museum began acquiring works by Andrew Wyeth in advance of its 1948 opening and now owns more than 60 works by members of the Wyeth family.
