Masters' paintings fetch record sums at auction

Paintings by Henri Matisse, Claude Monet and Pablo Picasso sold for tens of millions of dollars on Tuesday at an auction at Christie's in New York.

The artworks were part of the 2,000 pieces in the sprawling personal collection of the late billionaire David Rockefeller and his wife Peggy.

The auction was expected to be the most lucrative for a single-ownership collection.
