Dear Leslie,

Thank you for your help and patience.

The presented object appears to be a chiarascouro woodcut print on paper with 13 x 10
inches measurements. The print depicts Augustus with the Tiburtine Sibyl. This is an motif after the artist Girolamo Francesco Maria Mazzola PARMIGIANO (1503-1540). This artwork was made by an unknown Italian artist probably in the 16th century or later.
Comparable objects were recently not offered and sold on the international auction market.
This piece is in good condition and no severe damage is visible in the images.
A fair market estimation would be between 1.500 to 3.000 USD.
This estimate is based on recent recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
George
