WORKSHOP OF JOSEPH NOLLEKENS, (1737-1823), CIRCA 1810

Nollekens and his workshop are said to have produced over seventy replicas of this celebrated bust. Pitt refused to sit for the artist, so the likeness is taken from his death mask in 1806. The busts, sold at £120 each, and provided Nollekens with a steady income.
