The next story is historical fiction set in Cornwall. It's the tale of a love between a gypsy girl and a wealthy young man, who ends up making a huge sacrifice to save her from harm born of prejudice.
There's a fashion section much like those discussed regularly by Jacque Nodell in her Sequential Crush blog. Despite 1980 being at the tail end of the first wave of British punk, there's little evidence of this in the book. About the punkiest people mentioned are Blondie and Bob Geldoff. 1980 was, however, early in the emergence of the New Romantic genre in music (Duran Duran, ABC, Human League, Orchestral Manoeuvres in the Dark, etc.), something that didn't really cross the Atlantic at the time, and the clothes on these fashion pages seem a little more in tune with that trend than anything else.
There are also advice sections, like in the American romance books. Jackie has a greater percentage of these kinds of features, in terms of the number of pages they occupy relative to the comics, when compared to its American counterparts.
The final story looks at sibling rivalry, something that many readers with sisters could probably relate to and perhaps be provoked into thinking about.
None of the art is signed, and I have little knowledge of British comics generally, girls' comics especially. Of course that makes it all the more interesting to me. Hopefully you'll also derive some enjoyment from this excellent art.
Jackie has acquired a kind of cult status in recent years, but has long been an object of popular as well as academic interest. An early analysis of the comic written during the peak years of its popularity is to be found in Angela McRobbie's book Feminism and Youth Culture: From 'Jackie' to 'Just Seventeen'.
