What an unfortunate interruption to an episode of skinny-dipping on an alien planet, painted by Mel Hunter (1927-2004) for the April 1957 cover of If: Worlds of Science Fiction. Alien pervs seem to have been a thing with old Mel, as suggested by the earlier illustration to the right, also done by him (source: Wikipedia).
This issue of If: Worlds of Science Fiction is available to read and download at the Internet Archive.
Oh these are just fantastic, especially the first one with the adventurous skinny dipper. The mind can really wonder what’ll happen next. And dunno about anyone else, but those little guys look a bit hungry to me…
The second one reminds me of Barbarella.
And that Kylie Minogue video that referenced Barbarella.
Fond memories… ^_^
