This vintage map from 1851 shows a New York and Brooklyn very different from what we know today. Much of Brooklyn is still undeveloped, including the Navy Yards, most of Williamsburg and Bushwick. Queens is almost non-existant in the distance. The famous Manhattan skylines is nowhere to be seen, and the bridges have yet to be built.
