This is a vintage cowboy hat / llanero hat. 
Brought home from South America by my uncle. 
I believe it was made from palm leaf. 
It features a Cattleman Crease (the oldest crease found in cowboy hats)
The red tassel is suppose to symbolize something but I can not remember what.
This hat has a nice substantial feel to it.
