Found in the latest edition of Steve Cook’s newsletter. I’d never heard of this comic. Found a write-up of it on Lew Stringer’s old website. I can see why Steve held on to it – apparently it got a bit weird for a kids comic:
That change came quickly with issue 19, heralding a redesigned logo and more of an inclination towards its older age group. The masthead also now carried the words ‘Anti-Mysteron Edition’, and warnings about the Mysteron threat. As the Captain Scarlet TV series hadn’t even begun yet, this may have led to a few confused readers.
Unsurprisingly, the revamp didn’t help sales and Solo published its last issue dated September 16th 1967, still a week or two before Captain Scarlet began on ITV. Its chilling cover headlining the ‘Victims of the Mysterons’, – presumably photos of staff members at City Magazines.

Inside, Spectrum News tied in with the cover story, and was equally bleak, whipping up its young readers’ paranoia against an imaginary menace.
People used to wonder why the British comics crew produced such odd stuff.
