Tre-effe pewter plate with girl, bird and flower - Italian?

This is another piece I've just bought because I love the quality of the image in the centre. I know it's by Tre-effe and I think the factory might be Italian but I don't know anything else. Whenever I google the name I see floral plates by the same company for sale but none of the entries seem to contain any information about the factory itself. I have also struggled to find out anything about the designer, whose signature appears in the centre but is difficult to decipher. Any pointers would be much appreciated. It measures 31cm across.
