Dear Laurent, Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal. The presented object appears to be a painting made in oil paint on canvas with the measurements of 56 x 78 inches. The painting depicts a harbor with ships how they are common at The Channel and the North Sea. This painting appears to be not signed. The canvas is stamped by a canvas producer in Paris. This painting was made around 1900. Sadly no additional information for an artist 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 medium condition and there is no serious damage visible in the images provided. A fair market estimation would be between 250 to 500 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
