According to OCLC, there are less than a dozen copies of this Benjamin Franklin broadside in the United States and three of them are at Princeton. Folded into a stamped binding (see below), the undated broadside was published after 1790 (Franklin’s death) at the shop of Carington Bowles (1724-1793). Its twenty-five engraved oval vignettes (including a central Franklin portrait) were designed by Robert Dighton (1752-1814) to illustrate Franklin’s maxims.

Benjamin Franklin (1706-1790), Bowles’s Moral Pictures, or, Poor Richard illustrated: Being Lessons for the Young and the Old on Industry, Temperance, Frugality &c. By the Late Dr. Benj. Franklin (Manchester (Exchange St. and St. Anns Square): Bancks & Co., [between 1819 and 1839]). Graphic Arts Collection 2007-0083N

The biography for Robert Dighton (1752-1814) posted by the British Museum lists his shop at 12 Charing Cross; 6 Charing Cross; and 4 Spring Gardens Charing Cross, London. “A singer and draughtsman, especially known for designs for satirical prints, which he initially supplied to Carington Bowles and Haines. Later plates he etched, published and sold himself. Stole prints from the British Museum (see A. Griffiths, ‘Landmarks in Print Collecting’, BM 1996, pp. 10, 49-50, 60, 276-83). Son of the art dealer, John Dighton (q.v.). Father of three artists, Robert junior, Denis and Richard (q.v.), who seem to have worked together as a family business, with a common stock of plates.”–Britishmuseum.org
