Pair of 50s Rockabilly Butterfly Wall Lights

Pair of vintage rockabilly wall lights in the shape of a plastic butterfly attached to a gilded brass structure. Show signs of wear on the back of the metal structure which is not visible in use - see the photos. There are also some small defects on one of the wall lights visible in the last three photos. The electrical elements (cables etc ...) are original. Sockets to receive b22 type bulbs.
