While it's just a mural likely showcasing various primates and all of the great apes, notice the addition of an bonobo. It was mentioned in the Ragunan book by Hoofman (1993) that there was bonobo(s) at the time in the 1990's. This is likely the only depiction of the zoo's supposed bonobo, supported by the fact that all the other primates depicted here have actually been maintained by the zoo themself.
