This chart is a direct descendant of the original draught prepared by Dobrée and engraved by Emmanuel Bowen in 1746 (or earlier). In this version, there are no engravings of sailing vessels and there is still no reference to longitude and latitude.

From premises in Fleet Street, Robert Sayer traded as a print seller and map publisher either under his own name between the years 1751 and 1770 and 1784 and 1794, or in partnership with John Bennett as Sayer & Bennett in the intervening years. During his long business life he published a large number of maps by his contemporaries, Kitchin, Jefferys, Bellin, d'Anville and others as well as a re-issue of Saxton's Britannia of 1583. On his death his stock was taken over by Laurie and Whittle who re-issued his material in many varied editions.
