VINTAGE 70s Blazer

So this coat belonged to a Jazz music man. Which means it saw alot of action. I can't describe the threading , it's loomed? I have never seen another coat like this. One of a kind. This was worn performing and partying. Has been in sealed storage but becouse it is 50 years old there a a few signs of thread loss. I show in pic. Also looks like an old pen mark on inside. See pic. Very Unique, Vintage Tribal print. Very warm lining.
