A portrait of former unemployment office worker Sue Tilley by artist Lucian Freud could fetch $47 million [1].

The valuation highlights the extreme volatility and prestige of the modern art market, where a subject's ordinary background contrasts with the astronomical price of the resulting work.

Tilley met Freud while she was employed at an unemployment office. The artist chose her as a subject during the 1990s, leading to a series of portraits that have since become some of the most famous and valuable works of modern art [1], [2].

One of the specific works associated with Tilley is titled "Sleeping by the Lion Carpet" [1]. While Tilley was not a professional model at the time of the sittings, her image has since transitioned from a private study to a high-value asset in the global art trade.

Tilley said she is fascinated by the fact that the paintings now command multimillion-dollar prices [2]. The shift in value reflects the enduring demand for Freud's visceral style and his ability to capture the human form with unflinching detail.

Because the portraits were created decades ago, the current market interest underscores the long-term investment nature of Freud's oeuvre. The potential $47 million price tag [1] places the work among the top tier of contemporary portraiture valuations.

The massive valuation of Sue Tilley's portraits illustrates the 'celebrity' status accorded to Lucian Freud's subjects, regardless of their own social or professional standing. It demonstrates how the art market decouples the value of a work from the status of the sitter, instead pricing the artist's gaze and the historical significance of the piece.
