Very interesting award.
In August 1881 during his worldwide journey, King Kalakaua visited Vienna, Paris, Madrid, Lisbon, and London. Near the end of his time in Europe, while in Paris, His Majesty had this special medal created for 8 individuals. In the center is a rotating globe with a map of the world.
Seven of the medals ordered were given to the men who traveled with him in 1874 or 1881 - Messrs. Dominis, Kapena, Armstrong, Judd, Macfarlane, Hoffnung and Von Oehlhaffen - and Kalakaua kept one for himself (the very same medal that is pictured above).
