What kind of image is this? Is it a found image or created by the ethnographer (or a combination)? What is notable about its composition | scale of attention | aesthetic?

It is an image of text from a  housing developer in Pasadena combined with colors the author added as they interpret the text.  The use of a green-yellow-red highlighting to signal imagined past-present-futures is very catchy and works well to point to the linguistic agencies behind this promotional text.
