This is a mug shaped like a Duk Duk Dancer from Papua New Guinea. Like their dance costumes, the mug is conical in shape with large concentric circles for eyes. It has a transparent blue overglaze atop a bright yellow underglaze. More yellow than blue. The secret members of the Duk Duk society only appeared with the full moon. Justice was executed, fines extorted, taboos, feasts, taxes and all tribal matters were arranged by the Duk Duk members. In carrying out punishments, they were allowed to burn houses and even kill people. The society's practice has been dying out since around the start of the 20th century, but Duk Duk dancers are now featured as tourist attractions.
