Unfortunately I don't believe so. Some of the Girls' magazines have been getting partial re-prints; Jackie and Girl have some best ofs out, and there's at least one art-book style high-quality reprint of fix of so stories from Valentine Picture Story Library (which was a romance comic for older girls, but is pretty good also).
But my favourites (such as Bunty, the British Girls' Comic) are still only available via ebay or other second-hand outlets. Theyre not rare and not too expensive if you go for the yearly albums, but single-issue stuff is hard to find from before 1990, and by then the quality had taken a dive. Even though that was whe I started reading as a tot, heh. It's also possible to find "picture story libraries", which were manga-sized, longer stories printed all at once. I guess they had lower re-read value, or were kept safer because I *think* you had to send away for them?
As for School Friend, the only time I've come across the title was in the one auction I got this annual from, so the searching would likely be harder.
It would be great if they started doing comprehensive re-prints, though, because there are so many stories and the best ones really deserve to be read again.
