Stylized moai design, brown, with coffee-bean-like eyes. Vertical "dashes" are indented into the mug all over. Similar to Orchids of Hawaii design R-72. From the Mt. Fuji Inn in Omaha, Nebraska. There is another version from the Mt. Fuji Inn that is green with dashes.
There is also a version of this mug from this location that has no dashes, only woodgrain around the eyes, and was available in green or yellow.
