Thomas Cook produced portraits for the Gentleman's Magazine and frontispieces for book publishers, as well as a number of single plates in different genres for Boydell. However, he is best known for his reproductions of the works of Hogarth, published as Hogarth Restored in 1806. He also engraved the reduced reproductions of Hogarth for Nichols and Stevens's Genuine Works of William Hogarth (1808-17).
