@christies_inc: Known as 'the Empress of Pop,' the gallerist Ileana Sonnabend was synonymous with the radical breakthroughs of post-war art. She brought Andy Warhol, Robert Rauschenberg and Roy Lichtenstein to Paris while championing Arte Povera artists like Giovanni Anselmo in New York. In later years, she helped launch the careers of Jeff Koons and Bruce Nauman, guided by the seemingly counter-intuitive maxim 'I only want what I don't like!’ Stewarded by Ileana's adopted son, Antonio, this collection represents 'not just the vision of one individual,' says Chairman of Post-War and Contemporary Art Sara Friedlander, 'but really a time capsule of the post-war period.' 📅 21st Century Evening Sale | New York | 19 November
