Amazonian war clubs are really popular and hard to find. there is a great variety that spans Southern Americas from plain and decorative from short to the larger clubs.I have provided a link below to extensive viewing of such clubs.

These larger clubs are made of a hardwood like wamara or red pau. They are used as a fighting weapon or as a chiefs ceremonial staff. Amazonian clubs, as shown here have been incised with a pattern and then filled in with a white pigment. Particular to the Ashaninka or northern Amazonian tribes. Here is a link to the Ashaninka tribe detailing all their stats

Amazonian war clubs are hard to come being rather rare found in major collections and that of most top museums.

I will provide more close up pictures are available on request.
