Keeping warm for over 2 centuries

A Hudson's Bay point blanket is a type of wool blanket traded by the Hudson's Bay Company (HBC) in British North America, now Canada and the United States, from 1779 to present.  These were originally manufactured in England and used in trade with First Nations people, usually for beaver pelts.
We inherited our blanket from B's parents.  At least 50 years old, it still keeps us toasty on cold winter nights
