$85m portrait helps Picasso eclipse Van Gogh as art’s biggest name

Pablo Picasso has become the ultimate luxury brand. On May 3 at Sotheby’s New York Picasso’s rare and iconic 1941 portrait, Dora Maar au chat, became the world’s second most expensive painting when it sold for $85m (£48.3m) to a mystery buyer in the room, widely presumed to be representing a Russian oligarch.
