Pablo Picasso: Buste, November 21, 1970. John Richardson, curator of the exhibition at the Gagosian Gallery, singled out this painting as his favorite. ‘It’s very spooky, almost ghoulish,’ he told The New York Times. ‘At the time Picasso had been working on a painting of a black bullfighter, but this is a self-portrait. He clearly intended to have a magic element in his work.’
