‘Sue Tilley, the 60-something retired benefits supervisor and subject of British artist Lucian Freud’s monumental painting “Sleeping by the Lion Carpet” (1996), has travelled from her home in St Leonards-on-sea for an uncanny meeting with her oil-on-canvas counterpart before it heads to auction next month. The portrait, which Sotheby’s Europe chairman Olivier Barker says is “the magnum opus of Lucian’s work,” is estimated to fetch between £25 and £35 million ($33-45 million) at the Lewis Collection sale on 24 June. But how does it feel to have your body up for auction for tens millions of dollars and be bought by private collectors? We asked her.’
