Russia in Asia.

Uncommon miniature map of Siberia, Kamchatka and Hokkaido. The map is of interest for the use of "Little East Sea" for the sea between Japan and Korea.

Engraved by J.Gibson for "A New General and Universal Atlas Containing Forty five Maps by Andrew Dury". This miniature atlas published during the Seven Years' War.
The maps are typical for the period and well executed with great clarity. The plates are engraved in 1761 and in 1763 a second edition was presumably produced for the French market having all but nine with a French titles added above the top.
Published by Andrew Dury (fl. 1766-1777?) who was a British map and print publisher who operated out of Duke's Court on St. Martin's Lane in London. He was an accomplished mapmaker but substantially less successful than contemporaries such as Thomas Jefferys or William Faden, and his maps are relatively quite rare.
John Gibson (flourished in London 1750 to his death in 1792) was an English cartographer, geographer, draughtsman and engraver. Recognized as an important late eighteenth-century British cartographer, a contemporary of Jacques-Nicolas Bellin and skilled engraver, spent most of his life in prison because of several debts. He worked also for the Gentleman's Magazine for which engraved different decorative maps. He also published his own work in The Universal Magazine of Knowledge and Pleasure, The Universal Museum and The Universal Traveller.

Robert Sayer was a leading London print- and mapseller, mapmaker and publisher, active from 1748 to about 1792. In January 1747, his elder brother James jr. had married Mary Overton, widow of the print- and mapseller and publisher Philip Overton. It seems likely his freedom coincided with his joining Mary Overton; by 20th December 1748, he had taken over the firm and continued to run it until his health broke down in about 1792.

Thomas Kitchin was born in 1718, (one source claims it was August 1719). He died in 1784, so he was 66 years old when he died in St Alban’s, Hertfordshire. He was an English engraver and cartographer, who became Hydrographer to the King. He was the eldest of several children of Thomas Kitchin, a hat-dyer, and his wife Mary Birr. On his earlier maps he calls himself “Geographer to the Duke of York” who was presumably George III prior to his accession.
