When the Lights Go Out
I seem to recall that this strip was submitted by a member of the old Medusa Realm Message Board. After doing a bit of research I have discovered that it was published in a British girls’ horror anthology comic alled Misty in 1978, although without knowing that I had previously assumed from the style that it was at least 5-10 years older. The original page scans were black and grey, so they’ve needed a bit of tweaking, and the resolution isn’t great, but I haven't found bigger scans. I have however tried upscaling them and making various adjustments to try to improve the quality. I leave it to you to judge how well I succeeded.
Misty was one of at least half a dozen girls’ comics of the time, all of which published stories with the same type of hopelessly old-fashioned moral message: rebel against the status quo and fate will punish you for it.
