Vintage Brass Tie Clip etched pic of Native American with long hair & feathers

The tie clip is oval-shaped with a detailed profile of the chief, including long hair, a braid, and a feather. The clip has a patina, suggesting it is from the 1970s. I could not find anything similar to compare it too. I pretty sure it is brass. No marking on the back. It’s 1 inch in size.
