Dear Mohinder,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a painting made in oil paint on canvas with the measurements of 1.5 x 4 feet. The painting depicts a landscape with a river, a castle, and mountains. It is signed with the name "Brook" and was probably made in the late 19th century. Sadly no additional information for an artist with this name fitting in style and motif is given by reference books and databases.
Comparable objects were recently offered and sold on the international auction market.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 200 to 400 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
George
