The Port of Havana Docks Company is one of the symbols of American economic penetration into Cuba in the aftermath of the Spanish-American War (1898). This common share of $100, numbered B4611, was issued in Portland (Maine) in 1910. The company managed the port infrastructure of the Port of Havana, one of the most important in the Caribbean region, strategic for the sugar trade and manufactured-goods imports.

Bradbury Wilkinson worked for numerous states and companies around the world: its productions stand out for the fineness of their linework, the quality of the paper, and the precision of the engravings.
