Question

How is this map different from a typical map of the United States? What do the new names on the map have in common?

Answer 1

This map is only a portion of the United States, this is a very old version of it as well . 

Answer 2

It's not really a map - it's a political cartoon. I'm not sure EXACTLY it's meaning, but I'm pretty sure it's taking a jab at immigrants for coming to the US at the time, about how they'll change the way of life the whites had at the time (their fear at the time, btw).
