This is an image of Robert Aitken’s final known book ticket, dated 1800, near the end of his career. This later ticket, below, is found in a copy of James Anderson’s Recreations in Agriculture (London: T. Bensley, 1800), bound for the American Philosophical Society. An entry in Aitken’s waste-book, dated November 14, 1800, records the transaction: “Philosophical Society Dr. / To bing. Anderson’s Recreations / 2 vols in Sheep, 9 -.”  Quoted from page 25 in Willman Spawn & Thomas E. Kinsella, American Signed Bindings through 1876 (New Castle, DE: Oak Knoll Press, 2007).
