Published in Munich, this folio-sized work was the official scientific catalog documenting the newly discovered primates and bats from that expedition. It is considered one of the most famous, historically significant works ever produced on South American mammals.The vivid, highly-detailed illustrations were drawn by elite European wildlife artists, including Karl Joseph Brodtmann. They were captured on stone using fine lithography and subsequently hand-colored with watercolors to reproduce the precise texture of the animal's fur.
