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?

This is a found image and it contrasts well with the other images in the essay - very different to the Van Gogh painting immediately beforehand and completely different to the other two images at the start of the essay.  I feel like I want to know more about the people in the picture - what is happening?  Did he have to wait three months between being upgraded (apologies if this is not the right term)?
