"[Jennings] spent a year drawing The Daleks for the back page of TV Century 21 in 1965 but drifted away from comics. 'For 18 months I worked as a long-distance lorry driver. Not very exciting but I was broke! I took my ancient jeep up to the Yorkshire Dales where I travelled around painting pub signs and portraits.'"
And that was when there were a lot of comics selling in the hundreds of thousands of copies every week. How much more impossible it is to make a living as an artist today. To think of a talented creative craftsman reduced to driving a lorry because it wasn't possible for him to actually get a decent wage for his work. I'd say it makes me weep but mainly it just makes me furious.
Still, those are old battles lost long ago. Back to the present day: the collection's editor, Marcus Hearn, theorizes that the end of the strip runs straight into the TV/movie storyline Daleks' Invasion Earth. But that’s set in 2150 AD, whereas the human race in the TV21 strip are clearly much more advanced, with FTL spaceships, which implies that it leads into the events of The Dalek Book and The Dalek World, which are set in the 25th century. (Since that’s the Daleks’ first contact with humanity, they must use their later discovery of time travel to conquer Earth in 2150, presumably to prevent their defeat at the end of The Dalek Book.)
