NEW YORK — Three works by Andrew Wyeth owned by the painter’s close friend and admirer, actor Charlton Heston, area headed for auction.

They are being offered for sale at Sotheby’s New York on Nov. 18 by the estate of the Hollywood legend and his wife, Lydia.

The works are Wyeth’s landscape “Flood Plain” from 1986, estimated at $2 million to $3 million; “Ice Pool,” a watercolor of a winter scene created in 1969 that carries a pre-sale estimate of $150,000 to $250,000; and “Study for ‘Flood Plain”’ which the artist gave to Heston in 1991, estimated at $20,000 to $30,000.

Heston died in 2008; Wyeth passed away the following year.

The actor greatly admired the work of Wyeth and began a correspondence with him in the 1980s. It led to a long friendship and visits.

His first purchase was “Ice Pool,” which he gave to his wife as an anniversary gift.

In 1987, he narrated a documentary on Wyeth’s “Helga” period, a series of more than 200 paintings and drawings the artist created using his neighbor as a model.

The three works are on view at Sotheby’s Los Angeles galleries.
