That Romero's celebrated style turns up in Diana is interesting in and of itself. I only have a few Diana annuals, none of the weekly comics, but in those annuals there is a regular feature called 'The Fabulous Four', a girls' sci-fi futuristic adventure story. Artistically it is probably the best piece in a book that is generally full of high quality art. Below is the Fabulous Four story from the 1977 Diana Annual - enjoy!
I think we lost a lot when romance comics and these girls' comics went by the wayside. What is interesting also, to me, is that there were comics (and such high quality comics at that), produced for girls in the UK. We'd still have them today if there was a market, but they're gone, presumably because girls stopped buying comics. We've talked about this before, but perhaps somehow the publishers lost their audience by being unable to go with them wherever it was that they went, in terms of what they were looking for in entertainment.
