Dear Patrick,

Thank you very much for such a detailed answer. I certainly see the difference in the example, and, of course, I could not even hope that this plate is as old as the old mark on it. But In our times, it is difficult to imagine that to create a fake, people spent so much time and effort and drew with their hands, even if worse than the original, but they tried. I'm sorry for wasting your time for this fake stuff.

Since I bought this plate simply because it's cute and I'm not a collector or dealer, I will be happy to serve some cakes to my guests on it. Especially now that I know that this is an attempt to repeat the famous Delft.
Thank you again for your prompt and detailed response. I've learned a lot
Have a nice day

You have dispelled the last doubts and helped with direction. I'll try to search in Italy, I haven't looked there yet. Now it's even more interesting to find a manufacturer. I hope I will find and Delft  someday.  Thank you so much
