From 1978: OUTER SPACE, a one-shot (?) quickie entry into the SF magazine genre, spawned by the success of you-know-what.
It's a British title published by an outfit called Rathbourne. I stumbled across this copy recently, the one-and-only time I have ever seen it.
The cover is very "that'll do" but the contents were OK considering the undemanding times they appeared in.
