A set of five books, written by Terrance Dicks and published as slim, almost A4-sized paperbacks by Target Books in the UK in 1977. These are overviews of various subjects, with the Doctor in the guise of Tom Baker) as a guide. CONDITION – okay. The covers are all a bit scuffed & marked, but the inside pages are in fine shape. NOTE – these are NOT accompanied by the bonus posters mentioned on the front, however as the posters merely consisted of enlargements of the front cover of each title its hardly a huge loss.
