This is a really cool old film clip. It shows lower Broadway in 1903.
Here is the description provided by the Library of Congress.
The film shows a view which appears to be looking north on Broadway at the intersection of Wall Street, in front of Trinity Church. The sidewalk along Broadway is crowded with people, and the traffic in both streets is very heavy. A horse-drawn streetcar passes in front of the camera [Frame: 2814], with a sign giving its destination as the “Courtland and Fulton Street Ferry.”
