This beautiful figural bird figurine is by world-reknowned glass artist, Licio Zanetti. It appears to be a type of tern or perhaps a gull. Apparently, the internal coral piece is a device this artist has been known to use in other pieces. It certainly makes the all clear glass stand out. Approx. 10 pounds! Also, it measures approx. 15" tall - very large for his bird figures. History of the Zanetti company indicates that Licio stopped producing in 1989 (his son continues the company). Thus this piece was done sometime between 1956 (when Licio and his father founded the company and 1989 when he stepped down).
