This is an extremely rare Pende mask, made even rarer by conserving its finial -- in this case a pair of fish -- a detail almost invariably missing from older masks. 

The Pende are known for their fearsome pumbu masks, expressing the anger of chiefs and their power to punish.  By contrast, kipoko (various spellings) express the healing and nurturing  power of chiefs.  The mask forms part of the chiefs treasure and is kept in residence with other sacred objects.

The mask's exaggerated eyes, ears, and nose show that the chief knows everything.  he sees all wrongs, hears all complaints and can "smell out" witches.  The nonexistent mouth conveys the idea that the chief should be slow to speak the words of wrath. 

This outstanding example is one of the best I have seen, in or out of collections.  

Carved of soft wood (popular for masks because it is light to wear) this very old mask has suffered some damage and there are repairs to the brim.  Overall condition is good given an estimated age of around 60 years.

This is a fine old example of a rare and fascinating mask.  Extremely collectible.
