This is superb early 18th century map of Chesapeake Bay area.  Delaware is shown to be a part of Pennsylvania, favoring the claims of Lord Baltimore, and New Jersey is divided into East and West Jersey.  There is a lot of topographical and early settlement detail offered. Both Baltimore and Philadelphia are shown, and of course this map pre-dates Washington DC.  This map is based on the survey work by Augistine Herrman and was first issued by Christopher Browne in 1692 and then reissued by John Senex in 1719, which is the current map.  The prominent cartouche includes tobacco, a major regional product during colonial times.
