Kelvin's Tiki Mug
in 12 collections
The Kelvin's tiki mug gets its name from the foil sticker found on the bottom of many examples. It is believed to have been used at the Los Angeles Islander restaurant. The mug is brown bisque with glazed top and bottom rims. The tiki has football shaped eyes, a flat nose and an open mouth turned down at the sides. Its minimalist arms meet at its stomach.
