Dear Rich,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a serigraph on paper with the measurements of 33 x 33 inches. The artwork depicts a typical motif of the op-art movement and is signed with pencil, dated 1971, and numbered 8/25. The signature could be read as Meci or Meli. Sadly no fitting artist is mentioned in reference books and auction databases.
Works by this artist were recently offered and sold on the international auction market.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 100 to 200 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
