Hi Raul,

Thank you for contacting Mearto with your appraisal inquiry.
Xurxo Alonso has a small body of works that have sold on the secondary market at auction; likely this is because he is still alive and working and most of his works are sold through galleries, the primary market. In a retail or gallery setting, this would probably have a price between €1,500-2,500; the standard industry multiplier to fair-market would price this at €700-1,000
Based on the photos and information provided, and subject to examination, this is:

Xurxo Alonso (Argentinean, Born 1956)
