Dear Michael,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a charcoal drawing on paper with 25 1/2 x 19 1/2 inches measurements. The drawing depicts a still life with a sculpture, a bowl of fruits, and a violin. This artwork is signed in the middle of the motif by Robert DE NIRO (1922-1993) and dated (19)67.
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 1.400 to 2.000 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,
Gregory
