I own a native american braclet which has a star with the initials SB inside. this braclet was purchased in the 1970's. Can you tell me anything about the artist? It's been some time now but I believe I was told the name was Sammy Bill.
I do not have access to the books of American Indian marks. There are a few books out there that do have images of the marks and identify the makers. I suggest you check your local library and see if they can get you a copy of these books for your use.
