Of course, what we find "typical" has a strong element of subjectivity. For a person who is depressed, or one who is elated, or maybe has a strong sense of identification, there is no talking them out of the ideas and images they abstract from reality in order to represent a subjective truth to themselves.
Let's assume the images depict what they purport to. (I remember a big outcry in my town a long time ago when some ancient oak trees were felled. Outraged residents claimed that this was an act of wanton environmental vandalism, but it turned out that the trees were diseased and dangerous, and it was followed by replanting of new trees. Manifold are the dangers of amateur arborism.) Are the images any more "typical" of human mentality than those depicting love, kindness, ingenuity, courage, etc? In fact, cutting down trees to put up pictures of trees is so rare that we would struggle to find other instances of it. Like all such meaningful images, it is an abstraction selected from the flux of reality to make a point that someone wants to make.
A disabled friend of mine (now dead) once showed me this picture, and told me that - for her- it represented the best in humanity. It is of a mother bathing her disabled daughter.
I think it has just as much right to claim to represent "typical human mentality". It is just another confected abstraction, of course, but one that makes a different type of point.
