When the book Casket of Souls was published there was a competition whereby once the reader had defeated "the dread Bone Demon by uncovering the spell hidden in [the] pages [of the book]" the reader could send their answer on a postcard to "Department Sallazar" at Penguin Books. The winner of the competition would win the original golden Casket of Souls model, hand sculpted by Citadel Miniatures directly from the artwork of Iain McCaig.. The competition was only open to residents of Great Britain and Northern Ireland and the closing date was 14 February 1988. The name of the winner was to be available from 1 March 1988.
