The Terrible Trunk
From Atlas' Adventures Into Weird Worlds #5, April 1952, "The Terrible Trunk," drawn by Joe Sinnott, begs the question. Who would you throw into that trunk, if you had it, and could make someone--anyone-- disappear? Maybe a mother-in-law, ex-wife (or ex-husband), ex-girl or boyfriend. You could throw in presidents of certain countries, if you could get them away from their security guards, that is. The possibilities are endless. For sure, like Harry Deevers in the story, I'd toss in my boss.
All you'd just have to worry about is another trunk, somewhere else, where those people might reappear and come looking for you.
