Dear Itsik,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a painting made in oil paint on canvas with unknown measurements. The painting depicts a city view in the manner and style of Expressionism. This artwork would be dated stylistically around 1920 or shortly later. The composition and the details of the oil painting itself have weaknesses. The frame has a paper label mentioning the famous Gallery Stein. The label itself appears to be cut out in a not straight line with a scissor which does not fit with a highly-priced painting.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 400 to 800 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
