A work from Claude Monet’s “Water Lilies” series has been sold for more than $43.7 million at Christie’s.

The money will benefit the Hackley School in Westchester.

The painting by Monet, a founder of the Impressionist school, dates from 1905. That’s the year Monet began a feverish phase of paintings depicting his garden’s lily pond in Giverny, France. The work that was sold is considered among the best.
