Bagobo Shield Puzzler

[Clubs & Arrows]

Wouter,
Thank you for the pic with the woven helmet/hat. I completely forgot to include pics from the book that I mentioned as far as the wooden skull. I would love to know what the actual use was, since all they do is speculate on it's purpose in the book. I thought that perhaps the groove that goes around it was to tie something around it for suspension....but again just speculation.

Best,
Joe
