Chris's first commission to illustrate three Dr Who book covers came in 1973. Over the next few years he went on to produce over 30 covers for Target series, becoming something of a cult figure in his own right with the readers. The varied and exciting visual from Chris's illustrations, each one summing up the spirit of the programme itself, largely contributed to the success of the book series and introduced many of new devotees to the show.
