3 vintage Tribal items. New Guinea Spear. Amazonian Atlatl Arrows

Description

These are 3 vintage Primitive Weapons.
The largest is an old wood spear from New Guinea.
it is 72" long and is one piece of hand hewn wood with a woven portion at one end.
The other 2 items are Atlatl arrows from what is either the Amazon or Asian Tropical area as shown by the colorful Bird feathers.
They are both made of bamboo with plant fiber lashings.
31.5" & 69"
All items are in vintage as found condition.
I do not have any history of these items or know what tribes they may belong too.
The spear may be Sepik River.
Interesting additions to your collection.
Fun decorator pieces.
Thanks for looking.
