Hi, my name is*****'m a certified appraiser, and I'd be happy to help.
Can you please upload a photo of the signature?
It's here and I am researching.
I'm not finding anything under the name Feilli. Before I try other possibilities--did you find a Feilli gallery? Your comment makes it sound like you did, just wondering. "Looked at the Feilli gallery for comparables."
No, it's definitely not Antonio Frilli.
I'm unable to locate this artist, so I'll opt out. Perhaps another appraiser will be more familiar with it.
