I put a tape measure next to the photo of each print. They are on a heavy paper.
Hi again Susannah
Thank you for your appraisal inquiry with Mearto. The item presented appears to be another etching by Giovanni Battista Piranesi (Italian, 1720 – 1778) titled "View of the Piazza, and Basilica of S. Giovanni in Laterano" from the series "Views of Rome," created during the mid-late 18th century. Again, the "Piranesi F." inscribed to the lower margin denotes the print was printed by the artist's son, Francesco. Francesco preserved many of Piranesi's plates and continued to reprint them. The estimate provided is based on recent auction estimates and results of this work and other comparable etchings from the series. The estimate is contingent on a full condition report. Please note asking or dealer prices may vary. Thank you and please take care.
