This undated postcard from Zenith Interstate News Company offers a view of grain elevators on Rice’s Point, the Duluth-Superior Harbor, Aerial Lift Bridge and other waterfront locations.

The caption on the back reads:

Duluth-Superior Harbor ranks second in the world, second only to New York City in tonnage handled annually. More than ten thousand vessels arrive and depart annually from the Duluth-Superior Harbor. In this picture you see featured part of the great grain elevators and docks in the harbor. There are also the world’s largest iron ore and coal docks in this magnificent harbor.
