The renderings explore what other ethnic and religious groups would look like as stereotypical mascots.
The exhibit pokes fun at all cultures, complete with the Gangsta representation sporting a grill over his teeth and a gold chain necklace, Latinos appearing as a human version of Speedy Gonzalez, and even Africans as the indigenous stereotype with a bone through their nose.
However, the exhibit didn't just poke fun at people of color, but was an equal opportunity offender.
The German rendering is basically a cartoon Hitler with a swastika medallion around his neck. The Irish representation looks like a slobbering drunk leprechaun. White Folks are presented as hooded Ku Klux Klan members with a flaming cross adorning their white hoods, and skinheads have an X branded on their forehead and a spiked band around their neck.
Remember the "Fighting Whites" intramural team and its t-shirts from a few years ago? I said this parody was ineffective because it didn't caricature white people the way sports mascots have caricatured Indians.
Caricaturing white people as Klansmen does the trick. It portrays whites as xenophobic haters and killers--which is what the "Indian as savage" stereotype does too.
