The artist's signature is indecipherable, unfortunately, and the style isn't instantly familiar.
If I had to guess as to its origins, I'd say it looks like something from the UK's Starburst or maybe the short-lived Science Fantasy Film Classics, or maybe Fantastic Films.
UPDATED: I knew I could count on you folks! Star Kids Martin Kennedy and Glen Mullaly have both identified it as being the work of John Allison. It appeared in Science Fantasy Film Classics #3 from the Summer of '78 (the one issue I didn't have!). Looks like my guess wasn't that far off. Thanks, guys!
