OKLAHOMA CITY (AP) — An American Indian photographer and artist says Oklahoma law violates her constitutional right to free speech by restricting her ability to label her works as American Indian-made.

The Oklahoman (http://bit.ly/2gg217N ) reports Peggy Fontenot filed a civil rights lawsuit in federal court Tuesday. Fontenot says a change made earlier this year to the state's American Indian Arts and Crafts Act of 1974 is unconstitutional because it prohibits her from describing her artwork as American Indian-made in Oklahoma.

Fontenot says she could be guilty of a misdemeanor for marketing her work in that way while in Oklahoma.

The state law says an artist must belong to a tribe recognized by the U.S. Bureau of Indian affairs to use that label to market their works. Fontenot is a member of the Patawomeck Indian Tribe of Virginia, which isn't federally recognized.
