This is a mass-produced, commercial replica of the Journal as used by the tenth Doctor (David Tennant) in the new series. It was used in the episodes "Human Nature" and "The Family of Blood", and was full of detailed descriptions and sketches that the Doctor's false persona "John Smith" believed were simply strange dreams, but were in fact repressed memories of his time as a Time Lord. It includes a child-sized plastic ring similar to what the Master wore, though I am looking to obtain a more accurate metal version.
