Dear Muffi,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a decanter or bottle with the measurements of 151/2 inches height. The piece was made with blue colored glass with green accents and is engraved under the bottom with the name "A. Seguso". This signature could be identified with the glass artist Angelo Seguso.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 150 to 300 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With kind regards,
Georg
