This lamp was designed by André Ricard for Metalarte in 1970's.  The structure is in a tubular chrome frame where a white opaline plastic ball swivels. The plastic ball is divided in two, one has a opaque interior, which gives an effect that one part has light and the other doesn't. It can be also hanged in the wall, and be used as a wall lamp. Makers mark in the black plastic in the arms. It is in original and good vintage condition, with light wear consistent with age and use.
