Dear Mehdi, Thank you for contacting Mearto with your appraisal inquiry and for your patience. This is a Chinese painting of natura. These landscapes paintings were normally set in China and were, probably on rice paper, early to mid 20th century. Signed but artist not found. Very good condition. $ 200 - 300 *represents a fair-market value for auction purposes; retail or asking price may vary. Please let us know if you have additional items to appraise, and thank you again for using Mearto.
