Terrific and highly detailed world map in attactive wash color. Shows the limited extent to which the Northwest coast of America and NW Passage were known and explored. No sign of Antarctica. Robert Wilkinson was active in London as a cartographic publisher from 1785 to 1825. He produced a number of nice works, including a General Atlas and a re-issuance of Bowen & Kitchen's English Atlas, along with excellent large format separate maps.
