I just saw this picture in the Denver Art Museum mag. I thought it was very cool. If you check out James Luna's website there's some other very cool stuff there as well.
(Sorry the pic is so grainy. It's much clearer in the Museum magazine.)
Here's a bit of the blurb from the mag: "The self-portrait was intended to confront people's expectations about ethnicity. It is Luna's response to the prejudices about his mixed American Indian and Mexican heritage, and questions about who is a 'true Indian'."
