This high-resolution map was published in 1879 and is now freely available on the website of the American Library of Congress. We like a lot the perspective that the cartographer choose which makes it very modern for the time. Almost futuristic.

Zoom in, appreciate the monument illustrations and notice the historical details. Back then, the island of Manhattan was only connected to the land by a single bridge, the Brooklyn bridge. But technically it was only completed 4 years after this map was published. At that time there was no tunnels either. But as you can see on the map there was ferries to take passengers and shipments to the mainland.
