Italian Art Plate

Can anyone help ID this plate and signature? I think it's Italian. The plate measures 12" across and depicts KERBEROS (or Cerberus) the gigantic hound from Greek mythology, which guarded the gates of Haides. He was posted to prevent ghosts of the dead from leaving the underworld. Kerberos was described as a three-headed dog with a serpent's tail, a mane of snakes, and a lion's claws. Some say he had fifty heads, though this number might have included the heads of his serpentine mane.

Herakles was sent to fetch Kerberos forth from the underworld as one of his twelve labours, a task which he accomplished through the grace of Persephone.

Thank You
