Sue Tilley was working in an unemployment office when she met the artist Lucian Freud. The paintings he made of her in the 1990s are now among the most famous in modern art — and the most valuable.
“Sleeping by the Lion Carpet,” regarded as one of Freud’s masterpieces, is going up for sale at Sotheby’s on June 24, with a presale estimate of 25 million pounds to 35 million pounds ($33 million to $47 million).
