Just when it looked like the major auction houses had exhausted the supply of trophy consignments, another heavyweight collection has surfaced.

Sotheby’s has secured the collection of the late Argentine collectors Nelly Arrieta de Blaquier and Carlos Pedro Blaquier, a group of Impressionist and Post-Impressionist masterpieces said to be worth around $450 million, according Artnet News.

The consignment is expected to anchor the upcoming auction season and includes paintings by Vincent van Gogh, Paul Cézanne, Edgar Degas, Camille Pissarro, Pierre-Auguste Renoir and others.
