Antique Chinese Nuo Opera Wooden Theater Masks Pair

Found this pair of old Chinese Nuo masks today at the thrift shop. An excellent pair of masks if I say so myself. Great color, condition, craftsmanship, etc. Both masks have eye, nose, and mouth holes. As well as the cords to fit on the head. I don’t know who these masks depict but they look pretty royal. Both masks are about 12” tall and about 7” wide. Any info would be greatly appreciated!
