Tilley is the author of a biography of the Australian performer Leigh Bowery titled Leigh Bowery, The Life and Times of an Icon. Tilley was introduced to Freud by Bowery, who was already modelling for him. Freud painted a number of large portraits of her around the period 1994–96, and came to call her "Big Sue". He said of her body: "It's flesh without muscle and it has developed a different kind of texture through bearing such a weight-bearing thing."[2]
Freud's painting The Brigadier was sold for £35.8 million ($56.2 million) in 2015, four years after his death, replacing Benefits Supervisor Sleeping as the most expensive Freud painting sold at auction.[6]
The painting was exhibited twice at Flowers Gallery:
1996: Naked – Flowers East at London Fields
1997: British Figurative Art - Part 1: Painting at Flowers East
