Sir Walter Scott, photogravure of the 1820 bust by Sir Francis Leggatt Chantrey

From: Familiar Letters of Sir Walter Scott, ed. David Douglas, 2 vols (Edinburgh: David Douglas, 1894)

Photo-engraving involved transferring a photographic negative of a drawing, painting, or object to a metal plate, and then etching it in. The image is of the marble replica of Chantrey's bust at Abbotsford.
