Historia Posters has some pretty interesting old maps of the City. This one, designed by cartographer Bernard Ratzer and engraved by Thomas Kitchin, shows Manhattan and Parts of Brooklyn as it was before the American Revolution. There is also an intricate drawing of Manhattan as it appears from Governor's Island.
The original map can be seen at the New York Public Library, but Historia offers it as prints or on canvas.
