Dear Pratap,

Thank you for your request. The presented object is a giclee print with unknown measurements. This is a print after the famous painting "Portrait of a Young Girl" by Petrus Christus (1410/1420-1475/1476). This print was made in the second half of the 20th century.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 40 to 80 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
