Vintage Black Ogre (Natask) Kachina Doll Lamp from Ortega Galleries Arizona

Natask (Black Ogre) This Kachina Doll Lamp is over two-feet tall. A tag on the bottom states that it came from the Ortega Galleries in Arizona. The cord is old but I do not know exactly how old this lamp is. I am hoping that someone can help me date this interesting and scary piece. According to information on the web, these Kachinas make horrible noises and stamp their feet so that the rattles on their legs make an ominous sound. They are supposed to be able to eat a child whole. Hopi children heard stories of these Kachina and how they would kidnap them to cook and eat. Therefore, they were petrified of these creatures.
