Large cup and its sphere, in travertine, 1970s

Large cup, empty pocket and its sphere, in travertine, from the 70s. Work most certainly italian. Note, some discreet traces on the sphere (photo), otherwise together in very good condition. Slight flat under the sphere so that it holds without rolling, can also be used as a paperweight. Cup diameter 30 cm and height 3 cm // diameter of the sphere: 8 cm.
