Gunn, M., Ritual Arts of Oceania New Ireland, Milan 1997, p.80, fig.90, illustrates a very similar mask in the British Museum, collected in August 1875 in Katherine Harbour on the central west coast of New Ireland on the voyage of S.M.S. Gazelle. Another is in the Barbier Mueller Museum, Geneva (ill. opp.p.80, no.8) and one from the collection of Lt.-Gen. A.H.L.F. Pitt-Rivers was sold at Sotheby's (25 May 1999, Lot 152A). Gunn explains that the masks are exceptionally rare, only about a dozen being known, and that they may not be part of the malagan tradition found further north. Those with collection data come from the central and south west coast and may have links to other masks further south.
