Christie’s New York will offer Claude Monet’s Nymphéas, a 1905 view of the lily pond at Giverny from the iconic series that was the crowning achievement of the artist’s career. Estimated at US$30-50 million, the painting is from the Estate of Ethel Strong Allen, widow of the late Wall Street executive Herbert Allen Sr. In keeping with the Allen family’s long tradition of charitable support, the Monet and two Impressionist landscapes by Camille Pissarro and Alfred Sisley were bequeathed by Mrs. Allen to Hackley School, a not-for-profit K-12 independent school in Tarrytown, NY, about 20 miles from Manhattan. Proceeds from their sale will benefit the school’s long-term development goals.
