Dear Bob,

Thank you for your help and patience.

The presented object appears to be a color lithograph on paper with 35 x 28
inches measurements. This print was made after a print by
Michelangelo PERGOLESI (1760-1801). This print was probably reproduced in the 20th century (https://maps-prints.com/antique-prints-architecture-design/9719-antique-print-of-18th-century-architecture-elements-by-pergolesi-1780.html)
Comparable objects were recently offered and sold on the international auction market.
This piece is in good condition and no severe damage is visible in the images provided.
A fair market estimation would be between 40 to 80 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
