'Quadrifoglio' ( four- leaf clover) is one of the best known floor lamps designed by famous Italian Architect GAE AULENTI. With chrome stem and base and a clover shaped perspex shade, it was produced by Harvey Guzzini in 1974. This particular one is the caramel colour version, more uncommon than the white shade one. The internal part of it holds three standard bulbs while the concave shaped dome takes an extra one.It truly is a beautiful piece. Manifacturer 's label still on it.
