N/A Vtg Native Handmade Leather Buffalo Nickel 70s portfolio laptop briefcase bag

RARE piece of history. Rich espresso leather. 16”x13” very thick but soft supple leather I believe it is buffalo leather but not 100 percent sure. It doesn’t feel like any cow or horse leather i have ever seen. Beautiful hand stitching similar to clothes made by North Beach Leather in the 1970’s. Real vintage buffalo nickel detailing.
