This lot contains endangered species. Sotheby's recommends that buyers check with their own government regarding any importation requirements prior to placing a bid. For example, US regulations restrict or prohibit the import of certain items to protect wildlife conservation. Please note that Sotheby's will not assist buyers with the shipment of this lot to the US. A buyer's inability to export or import these lots cannot justify a delay in payment or sale cancellation.

The walrus is the only living species in the family Odobenidae and genus Odobenus. This species is subdivided into two subspecies: the Atlantic walrus (O. r. rosmarus), which lives in the Atlantic Ocean, and the Pacific walrus.
