A cross cultural fusion of animal-plant nature.  Symbols of tremendous historical and mythological value.  The ginkgo tree of ancient times is a true living fossil dating back over 270 million years.  The ginkgo thrives in harsh environments and is prized for its unique appearance, beauty, and hardiness.  Some current trees have been alive for over 1000 years.  Zebras are perhaps one of the most easily recognized animals to any child.  They are known from A-Z(ebra), and are truly spectacular animals.  Largely social animals, these wonderful beasts have never been truly domesticated.  When two zebras are together in the wild, they will stand side to side with their eyes facing the rear of their partner – and thus ensuring a 360 degree field of vision.  Both animals guard each other and form a synergy that allows them to see any predator or friend.  Together, the Zebra and Ginkgo have fused into a unique entity: a  far reaching product of hard work, determination, longevity, natural beauty and in turn spread goodness around the world.
