Images that reinforce social stratification?

I have an assignment to capture two dozen images (locally) of advertisement, products, etc that reinforce social concepts of gender, race, class, age, etc. I'm about halfway there but am running out of possibilities that aren't completely far fetched. I live in a small city (more of a town really) so there aren't tons of businesses or marketing or anything. I've already done some of the more obvious, like how certain toys reinforce gender roles..

Any ideas of things I could find in a small place? I'm really drawing a blank here. In an increasingly politically correct world, these things are becoming physically harder to find.
