Notes: Alcoa Corporation (Aluminum Company of America), based in Pittsburgh, began service in 1917 of its Alcoa Steamship Co. as part of the World War 1 war effort. It used at first foreign ships, then in the pre-World War 2 years until 1969 used ships with US flags. It is still in business (2024).

In the time period of this demitasse set (from 1949 into the 1950s), three vessels – the Alcoa passenger cargo liners Cavalier, Clipper, and Corsair – sailed to ports of call in the Caribbean/West Indies: New Orleans, Ciudad Trujillo, La Guaira, Puerta Cabello, Guanta, Port of Spain, Curaçao, and Kingston.

The company's logo, shown above in advertising from the late 1940s and 1950s, consists of a line drawing in gray-green of three seagulls on wing surrounding a ship, with the funnel of the ship shown with navy blue and dark red decoration. The logo interrupts a navy blue band flanked by dark red red pinstripes.
