A New York City auction house says paintings by Claude Monet and Pierre-Auguste Renoir are among 400 items that will be sold from a reclusive copper heiress' private trove this spring.
The Huguette Clark collection sale at Christie's comes after a feud over her estate was settled in the fall.
Some of pieces were acquired by her father, a Montana copper king and senator who founded Las Vegas.
Monet's "Water Lilies" is estimated to bring $25 million to $35 million.
Another masterpiece in the sale is Renoir's "Young Women Playing Badminton." It has a presale estimate of $10 million to $15 million. Both will be offered May 6.
Other items from the collection go on sale June 18. They include a Stradivari violin, Gilded Age furniture and rare books.
