Dear Nora,

Thank you for contacting Mearto with your appraisal inquiry.

The presented object appears to be a mixed media artwork on paper with 30 x 24 inches measurements. The artwork depicts a skull and was made by Ernesto YERENA (1986).
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 500 to 1.000 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
