View of the Nieuwe Maas in Rotterdam, with a large number of ships on the river. In the foreground steam tugs (with characteristic chimneys and chimney emblems such as those of the Volharding, the ship with a “V” on the chimney, in the front left), a large steam freighter in the center left (which probably sailed within Europe), sailing riverboats in the middle of the river as well as large ocean-going freighters.
