Complaint here:

Oklahoma's recent amendments to its American Indian Arts and Crafts Sales Act make it illegal to market art in Oklahoma as Indian-made if the artist is not a member of a federally recognized tribe.

The plaintiff, a member of a state-recognized tribe in Virginia who sells and markets her art in Oklahoma, alleges the act is unconstitutional and preempted by the federal Indian Arts and Crafts Act, which permits advertising of art as "Indian-made" for a broader population of artists, i.e., artists who are members of a federal or state recognized tribe, or who are certified as an Indian artisan by a federal or state recognized tribe.
