The 8-cent Pan American Issue stamp features an image of the Sault Sainte Marie Canal Locks. Completed in 1895, they were the largest and first electrically operated locks in the world.
The brown violet and black stamp was the first eight-cent denomination printed in more than one color. Another multicolored eight-cent denomination was not printed again until the 8-cent Statue of Liberty stamp of the 1954 Liberty Issue.
The 8-cent stamp of the Pan American Issue typically paid the domestic registered mail fee. When used with other denominations, it fulfilled large weight and foreign destination rates. The Bureau of Engraving and Printing produced 4,921,700 of these stamps.
