Dear Itsik,

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

The presented object appears to be a drawing on paper with the measurements of 22 x 14 cm. The drawing depicts an abstract structural composition and is signed with the monogram B and the dating 1922. The monogram is not identifiable and the motif or the style is not an argument for a known artist or artistic school.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 30 to 60 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
