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. Marked "Kon Tiki Tucson AZ" on back. The glaze is yellow.
Some of these were made by CARMAX ENT. (marked on bottom) and some are marked from FIRE HUT MFG.
