This is a recreation of the face and head art used in Kathakali, (Malayalam: കഥകളി), a "highly stylized classical Indian dance-drama noted for the attractive make-up of characters, elaborate costumes, detailed gestures and well-defined body movements presented in tune with the anchor playback music and complementary percussion. It originated in the country's present day state of Kerala [ South India] during the 17th century and has developed over the years with improved looks, refined gestures and added themes besides more ornate singing and precise drumming" (paraphrased from Wikipedia).
