What era of slum is that? If it's a 1942 slum then you're pretty much on point except for the dumpster as those types of trash recepticles didn't exist back then. If it's a modern slum, then the WW2 propaganda pic would have been painted over long ago, especially with some of the graffiti that soulcialism added.
