Pair of shell sconces

Pair of wall lamps in glass and gilded steel, in the shape of a shell. The diffuser of the sconces is made of thick opaque sandblasted glass, in very good condition. They are very decorative, with their art deco inspiration. Minor defects to report: One of the sconces has its golden metal faded (become silver, see one of the photos), on one of the sides of the tube carrying the bulb. This is not visible once the wall lamp is fixed, seen from the front. This same wall lamp has 2 small black dots in the glass (visible in the detail photos) The glass diffuser is very slightly different on this 2nd wall lamp compared to the first, in the left corner (as slightly polished), when looking at the wall lamp from the back. From the front, this is not visible and this difference from the 1st wall lamp is not visible. Screw socket e27. Dimensions of a wall lamp: height shell glass = 19 cm. Total height = 21 cm.
