Dear Saso,

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 unknown measurements. The painting depicts a landscape with an African market scene, painted in a somewhat haphazard style. It is signed with the name Muleba, which is assumed to be an alias because such paintings are typical of artworks made as decorative art in Asia or Africa in the last third of the 20th century.
This piece is in good condition and there is no serious damage visible in the images provided. A fair market estimation would be between 20 to 40 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
