Existing comment: Carte Particuliere de Virginie, Maryland, Pennsilvanie, La Nouvelle Jarsey. Orient et Occidentale.

This early navigational chart details the colonies of Maryland, Virginia, and Pennsylvania off the Chesapeake and Delaware Bays. It follows the tradition of early portolan (sailing) charts that were oriented with west facing the top, and north facing right. Colonial sailors relied on such charts for information on the water's depths, shoals, and inlets.
Pierre Mortier, Amsterdam, ca 1700.
