Hi there, I was wondering if anyone could please help me with a few things? I have been searching and searching without any luck. :-( I have this wonderful very old Italian clay vase it is painted blue and has a rope design wrapping around the main part of the body. The rope is in the natural colour of the clay. The bottom of the vase says Italy and has a signature or monogram of a Z plus d10742. Just curious if anyone would know what those 2 things mean and the time frame for it? Hope you can help. Thank you. :-)
