Dear Kaveh,

Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal.

The presented object appears to be a drawing on paper with
9 in x 10 3/4 in measurements. The artwork depicts a landscape with a well. It is signed with the name "Petromi" or "Petromi". Sadly no additional information for an artist with this name fitting in style and motif is given by reference books and databases.
Comparable objects were recently offered and sold on the international auction market.
This piece is in good condition and no severe damage is visible in the images provided.
A fair market estimation would be between 20 to 50 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
