Rare separately issued large format map of the Russian Empire (with an interesting projection of the Aleutian Archipelago), published in Berlin in 1769.
The map is derived from the work of Joseph Nicolas De L'Isle, with significant updates. J.N. De L'Isle was one of the most important figures in Russian cartography in the 18th century.
The map attributes the discovery of an amorphous Alaska to Bering and Chirikov, during their 1741 expedition.
The map was published by A.F. Busching, a Professor at the University of Gottingen, who published several geographical works.
Original hand-color. Engraving on three sheets of laid paper joined as one. Backed with old linen, at an early date. Some areas of insect damage, as illustrated. Ink Prussian censor stamps in the upper left and right corners (as required by publishing law at the time).
