Eucalyptus originally comes from Australia and its neighbouring regions. A koala's favourite food is the eucalyptus tree. The leaves contain loads of fibers, and poisonous substances that are extremely dangerous for other animals. The koalas have become accustomed to these toxins and can therefore eat eucalyptus leaves without any threats. They are very picky about which leaves they eat though! The poster has a printed white margin that frames the design.
