Copperplate, original colour, mm 635x995. A rare british double-hemispherical world map depicted in an unusual oblique projecton with London in the center of the eastern hemisphere, practically dividing the world into land and marine hemispheres. This innovative map was first published by Price with the new partnership of Willdey and Brandreth, probably in 1711. In other words, the map was created as part of a particular publishing venture that was specifically intended to expand the British market for printed maps. The Price-Willdey-Brandreth partnership ended just two years later. Willdey took control of the printing plates for Price’s world map and reissued it with substantial changes. Willdey had allegorical depictions of the four continents added across the top, perhaps in an effort to expand the map’s market; the allegories were designed and engraved by H. Terrason (fl. 1713-1717). Willdey also had Terrason fill the bottom of the map with a large number of icons depicting the other commodities that Willdey sold, like telescopes, a clock, a globe, an armillary spheres, compasses, a gun, a microscope, and a barometer as well as scissors, knives, buckles, monocles, spectacles, tweezers, and razors. The plates were eventually bought in 1749 or 1750 by Thomas Jefferys (1719-1771), who continued to realize a return on his investment by selling impressions of the map, although with the icons of the commodities removed. Very good condition. Minor reinforcements at folds and margins.
