The word "Ancient American Style" is used because of a law passed in the United States:

The Indian Arts and Crafts Act of 1990 was passed to protect Native American works mostly from Asian and other Companies creating works that were being passed off as authentic or made by Native Americans.

You can read on the regulations by clicking here:  Indian Arts and Crafts Act of 1990.

You don't see France prosecuting other countries because they are making "French Horns".
Apparently there is some confusing regarding the title of the Flutes by some, French Horns for example do not have to be made by Frenchmen, English Horns aren't neccessarily made by Englishmen.  The title of an instrument may not necessarily connect to a point of origin.  For example:  Great Highland Bagpipes are not all made by Scottsmen.  In fact some are made in the US and even as far out as Pakistan.  

We can give Dr. Payne (non-native) credit for helping restore an instrument that almost went extinct - but the Wasicu's (non-indians) in Washington probably don't even know this.

Keep in mind that there are many people who have some Native American Blood but are not recognized by the United States as Native American.  (In fact, there are a handful of tribes recognized by States but not Federal - the Indians that helped the Jamestown Colony have not been recognized federally - but hopefully they will this year).   Many Natives wanted to have nothing to do with the government (tired of lies and broken promises) and their ancestors fled into the hills or wilderness and stayed under the radar and are refered to as "Undocumented Indians".    The is act does not cover anyone that whether they are full blood, mixed blood, thin blood or whatever, they are not recognized.

Many of us feel that the US Government will eventually complete it's act of Genocide and there will be no one legally called a Native American in a few generations.

Some Flutemakers (native and nonnatve) got in touch with that board and it was agreed that the word "Style" added to the title is a legitimate way of identifing the product as a Native American Flute but the word "style" added indicates that the person is either non-native or might be a native that is not recognized by the BIA (Bureau of Indian Affairs).  Recently, extremists are creating a further wedge against full bloods and mixed bloods and it's now not even advisable to use the "Native American Style" in terminology.

I myself am not documented with any federally recognized tribe in the US.  I have some Cherokee and Lakota roots in my family line and I fellowship with Natives around the Little Miami Valley and others on the Internet. 

I can't afford to run into problems with this intrusive government, therefore my flutes will be referred to as Ancient American Flutes to honor the Ancestors that originally designed them.

If you want Flutes made by federal and state recognized natives then you're on the wrong website.
Later, I will place some links on this page to identify those who are recognized.
