Here's some fanciful pulp-science fiction magazine covers as satirized in the "Mars and Beyond" episode of Disney's Man In Space trilogy:
This segment spoofs alien invasion films of the day, and reaches a crescendo of mayhem more associated with Chuck Jones than Walt Disney. A Martian menaces a lady in distress by releasing a swarm of bats from its alien maw.
It reveals suction-cupped tentacles.
It can even crumble into a swarm of insects, then reform.
In full pursuit of the Earthling woman, a literal parade of inventive aliens marches past.
The Man In Space trilogy is available on the DVD set Walt Disney Treasures: Tomorrowland-Disney In Space and Beyond.
