Thank you for submitting your item for appraisal. This appears to be an african earthenware vessel or jar, enforced with leatherbands, most likely used to carry water. Shape and execution resembles earthenware pottery from Nigeria but other areas on this vast continent might have come up with the same shapes. This could be an old or only vintage possibly second half 20th century item. Traditional production techniques have not changed and due to the climate things easily acquire patina. The estimate is based on similar items offered or sold at auction.
