and there it is, the best looking Wacky of them all
that August 1975 issue is certainly a fun coincidence with its 'face in a planet' relative to when the Wacky was released, but the consensus timeline for 14th series makes it pretty much impossible to be an inspiration.
speaking of dates, that's an oddity on this one, where the spine has 1974, but the cover has 1998. Whoever put down the letraset date didn't notice what Norm had painted, or maybe thought it would be better if it was 'in the far-future'. The story title also looks made up by Topps, (Jay had author's names) and to me is rather lame.
Probably the closest of all the Wackys to Saunders older work on pulp magazine covers. It stays close to Jay's rough, but it's very much his own look.
I find no F&SF that match the image, but there are two much older ones (1963, 1953) that have similarities
