"Bringing the characters of Lord of The Rings to life in pewter is Royal Selangor and Dr. Graeme Anthony from Australia, whose designs and detailed sculptures vividly portray each unique character or setting." (from Royal Selangor website)
Royal Selangor obtained their license from Tolkien Enterprises, so the depictions are based on artists' renderings, not on the Peter Jackson movies (though there are some remarkable similarities in some pieces.) Now at over eighty items, the line started with goblets, then expanded to shot glasses and wine glasses. They have since added other glass forms, limited edition sculptures (including one in sterling silver), commemorative plates, and more. Some of their sculptures are designed with the chess board in, allowing a full set to be played.
