The mythology of the 1980s comics revival is fairly well established by now. A handful of writers and artists - many of them from the UK - invaded the American comics industry and made it a much more interesting place to be. Northampton's own Alan Moore was one of the key figures in that renaissance, and his work with artist Dave Gibbons on Watchmen is justifiably regarded as a landmark.
But the fans know that Watchmen didn't just come out of nowhere: before then, Moore had been doing work on one of DC's old monster titles - Swamp Thing - that paved the way for everything that was to follow. It was one of the first mainstream comic titles that actively marketed itself as being for an adult audience, ditching the traditional Comics Code Authority seal of approval. It showed that it was possible to take old characters and breathe new life into them, through a complete re-imagining of who they were. And Moore's influence can still be detected in the dozens of British writers who've worked for Marvel and DC in the quarter-century since then.
Fancy reading a comic that actually changed the medium? Because you can do that for free, now.
