70s ceiling/wall light

Elegant glass ceiling/wall light from the 70s, a real glass block, its relief patterns multiply the light, from the front and from the side: round globe in molded glass "rosace pattern" on a metal base, electrified with a resin socket (requires a screw bulb type e27 not supplied), 3 closing screws and fixing holes. As a wall light, ceiling light or table lamp, we imagine it in an entrance hall, a living room, a bathroom... Or elsewhere...
