In the spirit of the season
MYSTIC COMICS #7, 1941. One of Simon&Kirby's first covers at Timely, with some cool monsters. And Hitler, too. The Destroyer is one of those characters who didn't seem to last very long.
BLACK MAGIC #2, 1950 (issue corrected, I got it mixed up with v2#2, aka #8. Wish they numbered those books normally and clearly). Boy, that Halloween party rocks!
WORLD OF FANTASY #19, 1959. One of the not quite so long-lived Marvel monster books, this issue at least had a pretty cool Kirby monster, apparently inked by Christopher Rule, leading candidate for the inker of FF #1 and #2.
