December Books 7) Doctor Who and the Invasion from Space [by J.L. Morrissey]
I thought I was reasonably well-informed about the history of Doctor Who spinoff fiction, but was rather amazed to discover this 1966 46-page story, in the same format (and by the same publisher) as the Doctor Who annuals, in which the First Doctor prevents an invasion from the Andromeda galaxy with the help of a family who he has rescued (just before the story starts) from the Great Fire of London. Apparently the text is by J.L. Morrissey, who published half a dozen detective novels in the 1930s and 1940s; the artwork is by Walter Howarth, the World Distributors stalwart illustrator. The story itself is standard Who, let down by rather dodgy astrophysics and some awkward phrasing (note extract from first para here). But the characterisation of Hartnell's Doctor is bang-on.
