Doctor Who and the Daleks (short story)

Dr. Who and the Daleks was the name given to a series of short prose stories and relevant trading cards given as prizes in packets of Cadet Sweet candy cigarettes. They told of a war between the Daleks and Voords on Marinus that ended when both races teamed up to find a powerful object that's location was a mystery until it was discovered by the Daleks. The First Doctor (here called "Dr. Who") is present in these events and attempts to stop the Daleks and Voords. The prose leaflets encouraged the purchaser to remove the title "Dr. Who and the Daleks" and send it to Cadet Sweet in order to receive further prizes. Points raised in this storyline have never been raised again in any other form of media, making it's canon unlikely.
