Entitled: "The comet of 1811" The head of the Prince of Wales in the head of a comet. In the comet's tail the first profile head is that of Moira, replacing Sheridan who is the second place, followed by lords and dukes. The Great Comet of 1811, formally designated C/1811 F1, is a comet that was visible to the naked eye for around 260 days, a record it held until the appearance of Comet Hale-Bopp in 1997. In October 1811, at its brightest, it displayed an apparent magnitude of 0, with an easily visible coma. The Great Comet of 1811 was thought to have had an exceptionally large coma, perhaps reaching over 1 million miles across, fifty percent larger than the Sun. The year 1811 turned out to be particularly fine for wine production, and merchants marketed "Comet Wine" at high prices for many years afterwards. Aquatint by Charles Wills, published 1811.
