There is a traditional society among many of the Iroquois tribes called the Husk Faces or Bushy Heads. Even today these woven masks are used in ceremonies. Of course, many are made just to sell to tourists. This one was purchased in Canada about 20 years ago, measures 17 inches top to bottom, and is especially well made. Real Native American masks are highly valued by collectors. This one can be seen on page 96 of Masks of the World by Ibold and Yohn.
