Porcelains Piano Player, Cello Player, and singer

Hi; First for future reference...The bottom of any porcelain or china item is the most important view. You say there is no mark at all? They look as tho they could be a campodimonte copy. In my opinion u should have this hands on appraised by a good porcelain expert or failing that pay the 9.95 at www.whatisitworth to you. I am not aware of Campodimonte ever being unsigned but it is certainly very much in that style.... you never know, I'm not a porcelain person actually, So value wise it is either worth a great deal, or if a copy sadly nothing at all. worth finding out I would think
