This elegant study illustrates Ramsay's fluent drawing style. He conveys Horace Walpole's appearance and informal pose, seated at his writing desk, with both sureness and swiftness. The blue paper complements his confident handling of black chalk for the main outlines, with highlights added in white. The drawing relates to Ramsay's portrait of Walpole in the Lewis Walpole Library, Yale University, painted in 1759. Horace Walpole, the son of the Prime Minister Robert Walpole, was renowned as an antiquarian, writer and collector. He was also a great admirer Ramsay's work.
