I read Eagle too, more for the stories and the cutaway drawings of aircraft and locomotives than the history. Also my parents subbed me it, which they wouldn't for Beano or Dandy, because of its perceived wholesomeness. Keeping Morris on board as publisher was a smart move by Hultons. I don't think you can blame him for Cosmo, though - Hearst made him do it. He must have been pretty doddery by then.

Compared to American comics, the use of rotogravure made Eagle & Co a much higher quality product, nicer to look at and feel, supporting more elaborate and subtle artwork and half-tone effects. So the editors looked for content that would look good in colour and be cheap, and came up with the same old stuff about Clive et al. By my theory, the Americans missed out on having their version of history fed to them via comics, not through virtue, but because their presses weren't up to it.
