Tilbury - Public domain image of a steam boat

In front, on a broad reach of the Thames, there are people in two rowboats; beyond, near the center, are a brig and a sailboat; at the right are three steamboats, near a large white steamer. Farther away there is a sloop under sail, and in the distance there is a confusion of shipping, under a cloudy sky. On the river bank, at the left, there stands a massive building. The butterfly, shaded, is below the middle of the plate, near the left edge.
