So many questions:
1.) As it’s clearly not a real ape, why the need for the cage?
2.) Why did they anthropomorphize this particular primate? (i.e. Is it just whimsicality, or is it a statement of some sort?) [Most of the creatures are in animalistic poses–though often not to scale.]
3.) Did the chimp start off reading huge (Tolstoy / Dickens / Ayn Rand style) books, or did it have to work up to them?
