a.k.a. Humuhumunu kunukuapua'a, United States Cruise Lines Humuhumu
One in a series of unusual mugs created for United States Lines and reportedly never used. Shaped like an upright humuhumunukunukuapua'a (a kind of triggerfish), the state fish of Hawaii. Drink is poured in a large opening in the back. United States Lines operated for less than one year from 2000 to 2001. Marked as "limited edition", but no series number seems to be on the mug.
