"W. Graham Robertson" by John Singer Sargent (England, 1894). Notes from the Tate Gallery: Robertson was an author, painter and art collector. He was 28 when he posed for this portrait, in which Sargent depicts him as a London dandy, wearing a fur-collared full-length coat and leaning on a jade-handled cane. 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.
