Dear Henry,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a watercolor drawing on paper with the measurements of 40 x 47 inches. The drawing depicts two North African warriors on horses probably from Marocco. The painting is signed with the name "Gabrielle" and was made in the late 19th century. Sadly no further information regarding the biography of this artist is mentioned in reference books or similar databases.
This piece is in medium condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 150 to 300 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,
Georg
