Dear Itsik,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a painting made in oil or acrylic paint on canvas with the measurements of 22 x 18 inches. The painting depicts a colorful fish and was made and signed by Aldemir MARTINS (1922-2006). this artwork is quite small in comparison to other works that were on the market.
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 800 to 1.500 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
