I liked the argument that the visualization is trying to make. The visualization could be clearer to highlight the spatial distribution of where exactly the new symbol being built will be placed and how it is located with respect to the census distribution along racial lines. For example could you make the map into an actual boundary map and show with contrasting colors the census distribution, and then insert the image in the middle? And what do you mean when you ask for who is this a comeback--is this something you can show visually as well? Instead of a juxtaposition, how about two maps--one of the racial distribution, and one which is an imaged map of Muskegon as envisioned by the "pure muskegon" people?
The image is a little opaque in my view, so the sculpture is hard to make out as well as the map. To extend the ethnographic import of the image, maybe the two sources could be combined in a different way, not only in an overlap? Or maybe there is a way to make both easier to make see.
