“Pre-contact, stone carved Agiba skull racks from the Papuan Gulf are some of the most elusive objects to collect in New Guinea art. This example has the thick, sturdy quality of the most ancient examples. Like on all stone carved Agiba, on the reverse there is a notch carved out where a rope was passed to lash it upright in the ceremonial house.” Micheal Hamson
