A. Maurin (lithograph), printed by Villain, 'David Hume Esqr.', c. 1820, lithograph, New York Public Library, Emmet Collection of Manuscripts Etc. Relating to American History (EM2982), public domain · Lithographic portrait lettered 'DAVID HUME ESQr.' with 'A. Maurin' at lower left and 'Lith. de Villain' at lower right, an early nineteenth-century French print made well after Hume's death; held by the New York Public Library (Emmet Collection of Manuscripts Etc. Relating to American History, item EM2982). The scan was downscaled once from 3,528 x 4,831 pixels to 876 x 1,200 pixels; nothing was upscaled. Shown as a later print depiction, not as a documented sitting. Caveat: the New York Public Library item page was behind an anti-bot challenge, so the museum-side record could not be opened; the date 1820 is as transcribed on the Wikimedia Commons file page from the library record, and the basis rests on the age of the print (the lithographer Antoine Maurin and the printer both lived and worked in nineteenth-century France, so the print is far older than 1931 whatever its exact year). · Public domain (early nineteenth-century lithograph; New York Public Library scan)
