One of my favourite works in all of the primatological literature. The orangutan is great but my highlight will always be the iconic type illustration of the Javan gibbon, which was scientifically named in this book.
Detailed drawing of a Javan gibbon by Audebert walking upright (as they do) and facing the viewer. The artist drew a stuffed animal that is still in the collection of the Paris Natural History Museum and is considered the holotype specimen of this species.
