A tinted lithograph of the head and starboard-side quarter view of Green's Blackwall East Indiaman, 'Trafalgar.' She flies the pre-1843 Blackwall line house flag, in which a (red) cross overlays a (blue) square, in choppy waters. She is flanked by a small sailing boat in the right foreground and two larger sailing vessels in the left background. A second Blackwall frigate is identified as the 'Owen Glendower' below the printed plate and above the title and publication detail.
