Thank you for submitting your item for appraisal. This appears to be a late 20th century bronze or pot metal unauthorized cast in the manner of Giacometti, bearing a signature "Giacometti" and the number 7 of 30.
Such reproduction casts from China have been around since the 1990s, for apparent reasons they have a decorative value only. The signature and limited edition number are an attempt to deceive the buyer.
