Captain Marvel Adventures (1941-1953) #130

There are only two sounds in the world that send cold shudders down the spine of the World's Mightiest Mortal. One is the evil chuckle of the mad scientist Sivana. The other is the horrible laugh of King Kull, the Beastman. So it spells double trouble when both Sivana and King Kull attack at once in "Captain Marvel Battles Double Doom." Also features "Captain Marvel and the Famine Foiler" and "Captain Marvel Battles the Mysterious Invisible Monster."
