What paper did the Della Rovere family write on? Most definitely that produced in Fabriano. With the involvement of the paper restorer Enrico Fanesi of Senigallia, we contacted Artem in Fabriano. Since May 2004, we have been offering the public handmade paper with the watermark of the Oak tree bearing gold fruits.  Andrea Ippoliti is responsible for the preparatory drawings for these watermarks.
