"The most important work from Claude Monet's Waterlilies series ever to be offered at auction in Europe is expected to fetch about £18 million in London next month, Christie's said.
Monet's Le Bassin Aux Nympheas, one of an extremely rare series of four large-scale paintings signed and dated by the artist in 1919, will be on sale at Christie's in London on June 24.
It is part of one of the most important and valuable collections of Impressionist and modern art ever to be sold by the auction house in Europe. "
