Dear Jonathan,

Thank you for contacting Mearto with your appraisal inquiry.

The presented objects appear to be two watercolor drawings on paper with the measurements of 22 7/8 x 18 7/8 inches. Both drawings depict views of Haiti and are signed by Frank WALLIS (XIX-XX). Sadly no further information regarding the biography of this artist is mentioned in reference books or similar databases. He mainly depicted views from Italy and the United States.
Works by this artist 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 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,
Georg
