This very rare map was first published in George Bickham's fully engraved 'British Monarchy' c.1743. A little known later edition by George Bickham Junior was published by Laurie and Whittle in 1796 under the title 'A Curious Antique Collection of Birds-eye Views of the Several Counties'. Of extreme rarity in either edition, the first is known in only 7 examples. The maps are highly collected for their distinctiveness. This is an example of the map of the county of Devon from the third state. For this the map is shortened slightly and a simple 'Devonshire' applied for a title.
