Thank you for contacting Mearto with your appraisal inquiry.
The presented objects appear to be two serigraphs or lithograph in colors prints with the measurements of 24 x 24 inches each. Both prints depict abstract motifs and are numbered and signed by hand in pencil. Sadly the signature of the artist is not clearly readable. All possibilities or variations of the reading I see there does not lead to a known or listed artist. These prints were made in the late 20th century.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 80 to 160 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.
With kind regards,
