Note: Once thought to be by Thomas Gainsborough, this portrait was attributed to Gainsborough Dupont from photographs in 1981 by Sir Ellis Waterhouse. In his written opinion of the work, Sir Waterhouse notes that the treatment of the ruff and the tassel are characteristic of Dupont and not Gainsborough. He also notes that the original Gainsborough portrait of William Pitt is in the collection of the Art Gallery of Havana, bequeathed by Oscar Cintas. Dupont painted another portrait of Pitt which was offered at auction at Christie's, NY, 25 May 1999, Lot 83.
