Dear Paul, Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal. The presented object appears to be a etching on paper with 22 x 30 inches measurements. This print has the title "Rovine del Tempio supposto di ercole nella Citta di Cora" and was made after design by the artist Giovanni Battista PIRANESI (1720-1778). This print comes from the publication "Antichità di Cora" and was published several times after the first publication in 1764 in Rome. This appears to be from a later publication of the 19th century. Comparable objects were recently offered and sold on the international auction market. This piece is in medium condition and no severe damage is visible in the images provided. A fair market estimation would be between 350 to 700 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, George
