What's wrong with this picture? All but one of the kids are dressed as things that are imaginary, or historical (if not extinct), or whimsical, or generic. Just one of them is attired as a stand-in for a living people--a living people who are still living, despite the U.S. government's efforts to kill them off. And yes, some of these people do, today, wear a feather headdress or paint their faces in ceremonial gatherings, although many do not.
Kids look cute dressed as bumblebees, or robots, or ninjas, and there's little danger that their fertile minds will form opinions about these things they will carry into adulthood. But what of the little Indian? What does his costume teach? If this is what an Indian looks like, does that define, for children, what all Indians are? Can an Indian be a lawyer? Do Indians live in houses? Do Indians speak proper English, drive cars, or even wear underwear? (And how come he doesn't have a dead crow on his head like in the movie?)
This is a funny commercial except for the stereotypical Indian costume.
Alas, the nature- and fantasy-based costumes indicate that Indians belong in the natural or fantasy worlds. So the commercial is telling us Indians aren't modern-day people. That's false and stereotypical.
