I am one of the authors of this book & I would describe it as a book focusing on the basket caps made by the Native American basket weavers of Northwestern California, including the Yurok, Hupa, Karuk, Tolowa & Wiyot. The book is fully illustrated both in color & black & white, and contains interviews and other priceless information about the weavers of these beautiful ceremonial & work caps. It is the most comprehensive publication on these baskets & the their makers.
