The Friendly Ghost, Casper #83

The cover of this 1965 Harvey Comics entry sets up a delightful mismatch: a hulking, green-skinned Martian in a bulky red spacesuit bears down menacingly on poor Casper, who scoops up a frightened little squirrel and makes a hasty exit while woodland creatures scatter in every direction. With a sleek flying saucer streaking across the orange sky and the bold tagline "Visitor from Mars," issue #83 promises the kind of warm-hearted, good-natured fun that made Casper such a beloved fixture of kids' comics in the mid-1960s.
