Dear Suzanne,

Thank you for your request. The presented object is a vase with the measurements of 29 x 18 cm. It has a red eosin glaze and is stamped by Zsolnay. This Hungarian company was famous for is iridescent eosin glazed porcelain and is especially known for its Art Nouveau design. This golden hallmark was used between 1924 and 1970.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 200 to 400 GBP.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
