Little drawbridge, Amsterdam - Drawing. Public domain image.

Spanning a canal is a small lifting-drawbridge supported upon piles, beyond which are trees at the right, and buildings seen below projecting branches at the left. In the center, above the bridge, rises a church steeple. Underneath the bridge, boats are seen on the canal and trees on its banks. There are three men, a woman, and a girl on the bridge, a woman in the street at the left, and two men on one of the boats. There are reflections in the canal and clouds in the sky. There is no butterfly.
