Ugo Sartoris Sculpture, 1957, Italian(?), "David and Goliath"

My Godfather, the Art Collector, gave me this piece in one of his moves. I was thankful, yet never displayed it as it is really more gruesome than my style! I believe this must have come from his father, as it is not my Godfather's style either!! I looked up what is sculpted on the bottom, Sartori(')s 1957. The father and son are both Italian artists, more famous for their leather theatrical masks, but the father was a sculptor before that, and I have sent photos to his son, who is excited to see if it is his Dad. I totally lucked out finding the son when I wrote to a random Italian art expert who happened to know the Sartori's. That is all I know. Maybe it is not the same, has anyone ever heard of a sculpture Sartoris?? The faces are rather haunting, and it stands just shy of ten inches. It is VERY heavy. Any ideas out there in CW world?? As always, my greatest appreciation, Michelle
Thanks to Marco Giunta and the artists neice Michela, we have ascertained that this is by Italian Ugo Sartoris from his early bronzes. He was also well known for his master Goldsmithery. Ugo's brother. Alberto Sartoris is also a renowned Italian artist in the medium of paint.
