Mill Mountain ZooSuzanne Barret Justis, a professional wildlife artist from Kingsport, Tennessee, is donating her portrait of Nina, a cougar that was donated to Mill Mountain Zoo several years ago. The work will hang in the gift shop and visitors will be able to purchase raffle tickets for an opportunity to own the portrait. All proceeds will be used to support Mill Mountain Zoo’s ongoing efforts towards matching the $50,000 challenge issued by the Alexander McCausland Trust. Justis has work hanging in the permanent collection of the Dallas Zoo, the San Antonio Zoo and is working on two pieces for the Lincoln Park Zoo.
