Sometimes when I start with a clip which is this generic, I just hit the Random Page button on Wikipedia* to generate some oddball associations and get headed down some kind of track. In this case, I hit a region of Kenya and started thinking about safaris, which would have been big in this time period for this class of people, judging by the art.
How I got from “How was your safari?” to this, I am not sure, and I’m a bit scared to find out.
*Yes, I still have huge hot-button issues with Wikipedia’s notability policies and the editorial abuse thereof. Wikipedia does retain many uses, and this is one. But there are a vast number of other uses it has lost because it is crippled by an autoimmune disease.
