Formia is a town and commune about halfway between Rome and Naples !! I assume Vetri is the artist name and is in the Murano area !! Not much info but there are a few of the Birds by this artist listed at about $150. and up !! Check the sold items on ebay to see if they are moving at that price !! There are several listed !! Would help to know the name of the piece or the series it is from !!
There are a few new birds listed at $29.95 !!
