Margaret Truman Daniel, the daughter of former U.S. President Harry Truman, stands to make as much as 500,000 pounds ($1 million) by selling a Winston Churchill painting at Sotheby's in London on Dec. 13. Churchill, who led Britain through World War II, gave Truman the landscape painting, "Marrakech," in 1951, Sotheby's said in a statement to be released today. Margaret Truman carried the picture home to her father in Missouri from London, and inherited it after he died in 1972, Sotheby's said. Prices are rising for works by amateur painter Churchill. Last year, a Moroccan scene given to U.S. General George C. Marshall fetched 612,800 pounds. In July, Sotheby's sold a view of Churchill's English home, "Chartwell Landscape with Sheep," for 1 million pounds, a record for the late premier. The Marrakech landscape, showing the Atlas Mountains behind the town,"is about as presentable as anything I can produce," Churchill said in a note to Truman, according to Sotheby's. Churchill, who died in 1965, was U.K. prime minister from 1940 to 1945 and again from 1951 to 1955 while Truman was U.S. president from 1945 to 1953. They first met after Germany's defeat, when they sat with Stalin at the Potsdam Conference near Berlin to decide the future of Europe, Sotheby's said. Churchill's letters are auctioned frequently, and there are so many that they sometimes fail to sell. Churchill, famous for his cigar, V-for-victory sign and wartime speech declaring "We shall fight them on the beaches," served as a legislator under six monarchs from Victoria to Elizabeth II, according to the Churchill Museum Web site. He published 60 books, won 16 out of 21 parliamentary elections fought from 1899 to 1959, and served 13 prime ministers. The Churchill Museum in London opened in 2005, marking the 40th anniversary of his death, as part of a 13.5 million-pound restoration and expansion of the once-secret underground headquarters known as the Cabinet War Rooms. Churchill memorabilia also are on view at Blenheim Palace near Oxford and Chartwell in Kent.
