This photo is a close up of a Hanuman mask, the Monkey King of the epic poem, Ramayana (known as Riemke in Khmer). The story tells of the banishment, travels, and return of Prince Rama and his wife Sida. Hanuman gathers all the monkeys to help Prince Rama rescue his wife Sida from Ravana. Originating in India, the Ramayana is now found throughout Southeast Asia.
