Vintage white ceramic up-and-down pendant light

Hello, Here is an elegant umbrella-shaped pendant light in white ceramic, dating from the 70s. It has a very practical up-and-down system for varying the lighting atmospheres. It is in a very good condition, with only three tiny paint chips on its top, visible in the photographs, as traces of time. No shocks or cracks are to be reported. It will work with an e27 bulb (not included). Thank you for your visit.
