I saw this on E-bay too and thought it was really pretty too. But since I don't know enough about millefiori and identfying it, I didn't bid. But I thought this had a gorgeous look to it. Very striking! I didn't realize it had an identifying mark on it. How clever is that! I think it would be awesome if the makers did something similar (ingraining the item in the glass) with an ID that could be traced to date, time, maker, and design.
