"Unusual Tales", a series presenting Steve Ditko's comics from 1957 to 1959 that are in the public domain.
"The Hostile Planet" is a 5-page story first published in Charlton's SPACE ADVENTURES #27 [1959], detailing two visits of the peace loving people of Neptune to Earth, with similar but increasingly dangerous results. I especially like the way Ditko draws the alien faces in this one.
But before the story, some links:
STATIC, MOCKER and MISSING MAN volumes available
New issue now available
Hulk/Torch team-up inches closer every day
Scans in this series generally adapted to my personal tastes from those copies
