signed and dated `Claude Monet 1919' (lower right)
oil on canvas, 39 1/2 x 79 1/8 in. (100.4 x 201 cm.)
In June of 2008, Le Bassin aux Nymphéa by Claude Monet sold for a world record bid of £40.1 million (that's $79,138,799.84 USD at today's prices before commission etc).
The fact that the auction attracted such a high bid is probably because this is a large Monet - and those rarely come on the market as most are in museums. It's only ever been seen in public once and is part of a particular series of paintings of the waterlilies in the pool at Giverny which are seen as being very associated with the beginning of abstract art. The painting is of the water and the Nymphéa and the reflections in the water of of the sky, clouds and trees above.
The previous highest price paid for a Monet was set in May of 2008 when Le Pont du chemin de fer à Argenteuil (1873) was sold for £21.5 million / $41 million in New York.
