This small Tiki mug has a big belly button, oval lips, and angular eyes. Different glaze colors have been seen, ranging from dark matte brown to lighter shades of matte brown. Lighter, sometimes white interior. This mug was used at The Beachcomber in the Mayfair Hotel at Berkeley Square, which is now the Radisson Edwardian May Fair Hotel. The design can also be seen on the front cover of the 1960s Beachcomber Dinner Menu. In period commercials available online, this mug and other matching pieces can be seen in use.
