Graham Robertson was an author, painter and collector who bequeathed to the Tate Gallery more than twenty paintings and drawings. He was twenty-eight when he posed for this portrait together with his eleven-year-old poodle, Mouton. John Singer Sargent presents Robertson as a London dandy, wearing a fur-collared full-length coat and leaning on a jade-handled cane. In his autobiography Robertson recalled that Sargent had insisted he wear the long coat even though it was summer. He also tried to make Robertson look as thin and youthful as possible.
