Explanation:

I hope that this is the right answer although I could not find about what speaker and artwork is about. I will tell you some information about Harlem so you can find it yourself.

Harlem does exist so it is not a made up city and since it is not rich and white neighborhood I also think that this is not the answer to this question.

Besides, correct answer can be also that the speaker is trying to escape to it, but since I don't have appropriate information, you must find it yourself.
