Flamsteed, John and James Thornhill, Virgo, 1729, plate 6 from the first and largest edition of the famous Atlas Coelestis, later hand-coloring, double-page folio 25.5 x 21 inches, in a chunky wood frame 28 x 32.5 inches, according to the Smithsonian Museum "This chart extends from 65° to 115° North Polar Distance and from 11h to 15h Right Ascension. It is drawn on a Sanson-Flamsteed sinusoidal projection. It shows the stars of magnitudes 1 to 7, with the brighter ones identified by Bayer letters. Working from Flamsteed’s catalog and manuscript maps, Abraham Sharp drew the coordinates and positioned the stars. James Thornhill ... drew the constellation figures." Maps from the first edition are quite rare.
