Dear Lamya,

Thank you for your request. The presented object is a painting made in oil or acrylic paint on canvas with the measurements of 70 x 100 cm. The painting depicts a sea battle between ships in the design of the 18th century. We see a signature by Longapetti. Sadly no further information of the biography for this artist is mentioned in auction records or similar databases. This painting was made for decorative purposes in the last third of the 20th century.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 100 to 200 USD.
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
