The design of this mug is borrowed from Thor Heyerdahl's Kon Tiki boat, which used the design of a South American sun god, Kon Tiki. Forehead has three sunray-like dashes, lips are two horizontal lines. OMC sticker on bottom. This version is from the Bali Hai in Lynnfield, Massachusetts.
"Bali Hai" is written horizontally across back. There is a similar mug for the Bali Hai in Northport that has "Bali" stacked above the "Hai" on the back.
