Robert Sayer, Printseller and Publisher
In 1747, Robert Sayer's elder brother James married Mary Overton, owner of the map and print business of her late husband, Philip Overton. A year later Robert Sayer acquired both her stock and her shop and began running it himself. From his London office on Fleet Street, he continued to publish the Overton stock while acquiring and expanding the business with plates from other printers, including maps, portraits, and nautical engravings. Sayer became a leading figure in the print, map and chart business; he took advantage of common production facilities and distribution channels and exploited the expanding markets in all three fields.
