Note 403 — A BOOK FOR A RAINY DAY (continued 3)
Reading edition
“Mr. Hillier, I believe, was of the same family as the late Nathaniel Hillier of Stoke, near Guildford, one of whose daughters married Colonel Onslow. He was a most extensive collector of engravings, and his cabinets contained numerous rarities, but he spoiled all his prints by staining them with coffee, to produce, as he thought, a mellow tint, but by which process he not only deprived most of them of their pristine brilliancy, but rendered their sale considerably less productive” (Smith). The trick of staining prints with coffee was once fairly common among collectors.
