Thank you for submitting your item for appraisal. This appears to be a serigraph by columbian born artist Willy Ramos titled Vase IV, wich is listed with a size of 65 x 50 cm. Serigraphs by the artist have no sold at auction so far. The estimate is based on comparable watercolours by the artist sold or offered at auction and the fact that original art would sell much higher. "Asking prices" in the trade can be higher and vary.
