Dear Simon,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a painting made in oil on copper with the measurements of 14 x 12 inches. This painting depicts an Adoration scene and was made in the second half of the 17th century. This painting shows similarities in its style and composition to works of Frans III FRANCKEN (1607-1667).
Works by this artist 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 2.500 to 5.000 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
