[Untitled Sea-Atlas of the Western Route to the Americas].
Elephant Folio (628 by 385mm). Twelve double-page engraved charts, pasted back to back. Contemporary vellum-backed blue paper wrappers pasted to the reverse of the outer charts. The cover and first map with substantial loss; the rear cover and map of the Indian Ocean with a hole. Some light staining, more so for the chart of the West Indies, pencil annotations, but a reasonable example of the type. Housed in a quarter morocco, clamshell box. [Amsterdam, Gerard van Keulen, 1734.
