On the right: "Grip on Life" art by Alex Toth from The Unseen 13, Nov/53.
On the right: "Your Grave Is Ready" art by Ross Andru from The Unseen 9, Mar/53.
On the bottom: "Atom Bomb!" art by Wally Wood, Two-Fisted Tales 33, May-June/53.
(Toth and Andru were inked here by, respectively, Mike Peppe and Mike Esposito, but the pencillers' layouts were what Carrabotta took.) I wonder how many swipes I've missed in this and other Carrabotta stories, when I happened to chance upon just these three source panels.
By the way: "Till Death Do Us Part" opens with a four-panel tier before the splash panel, and at one point someone says "Ow-w-w!" The unsigned writer is Hank Chapman.
