A set of large marble spheres

A sculptural set of 7 large C20th marble spheres, possibly from a fountain. The set comprises 1 huge sphere at 50cm diameter, 3 medium at 40cm diameter and 3 smaller at 30cm diameter. These would have been quite expensive to produce, each having been milled from sizable blocks of marble and now offering the possibility of impressive sculptural objects for interior or exterior use.
