Yurok California Indian Bow from Northern California made of Yew wood.  Black pattern on faint red background.  Back is painted black.  These are almost never available.  Estate find.  35 3/4″ long by 2 3/4″.  See photos for detail.
The last one sold on eBay was several years ago came from me. It sold for $3000. The paint was in better condition. The price I have it listed for is $300 less than I paid for it. I also have a Miwok sinew backed bow, one of about 7 in existence, one Chumash sinew backed bow, one of two in existence and one Chumash self bow found in the hills behind Similar Valley in the 1920’s. Only a few of those in existence. Let me know if you are interested in those. The price on the these is very high so you must be a serious collector for inquiries.
