I just found a small paperweight that is signed on the bottom. The signature looks like zillo, to me. It is in red, and appears to be "under" the glass. The only hit I've gotten on the name "Zillo" when searching Google is for Andrea Zillo, but I can't find anything on that artist's work or how her (his?) work might be signed, or even when she/he was working. If anyone has any info on this artist or can point me to a site that might have information about this paperweight, I'd appreciate it. Thanks very much.
