NEW YORK (Reuters) - Important works by Impressionist painter Pierre Auguste Renoir went unsold at auction on Tuesday, while a painting by Claude Monet and a drawing by Vincent van Gogh fetched more than $5 million each. Renoir`s "Young Girl Holding a Bouquet of Tulips," estimated at $15 million, and his "Dancers in a Studio," estimated at between $5 million and $7 million, attracted no buyers at the Christies sale in New York. Another Renoir painting, "Seated Nude," sold for $2.8 million. Estimates valued that work at between $3 million and $4 million. Monet`s "Waterloo Bridge", estimated before the sale at between $5 million and $7 million, went to a private Asian buyer for $5.3 million. A drawing by Vincent van Gogh, "Boats on the

Beach at Sainte-Maries-de-la-Mer," sold for $5.1 million. It, too, had been estimated at between $5 million and $7 million, and was considered by the painter to be one of his best drawings. A landscape by Paul Gauguin, "Les Dindons," sold for $2.9 million. Two records were set at the sale. Gustave Courbet`s, "The Gust of Wind," estimated at between $800,000 and $1.2 million, fetched $2.3 million, a record for the artist. And a painting by pre--Impressionist, Pierre Cecile Puvis de Chavannes, "The Childhood of St. Genevieve," sold for $937,500, also a record for the artist. The auction will continue on Wednesday. A report on Tuesday said Microsoft Chairman Bill Gates paid a record $30 million for an American painting when he bought the last major seascape by Winslow Homer that was left in private hands. The New York Times said Gates bought "Lost on the Grand Banks" at a recent private sale.
