One Panel #290-292: The Bigger They Are, the Harder They Fall

From "The Giants of Professor Zee" by Jerry Siegel, Paul Cassidy and Wayne Boring, Superman #8 (January 1941)

Is that a giant Lex Luthor? Oh wait, no, Lex isn't bald yet. So it's the Ultra-Humanite, right? No? Nope. This is one of a couple of synthetic giants created by mad scientist du jour, Professor Zee, who dies crushed under the heel of one of his monsters. And they all fall off a mountain and die. Aw.

From Superman: "The Preston Gambling Racket" by Jerry Siegel and Jack Burnley, Action Comics #32 (January 1941)

Speaking of falling, sometimes you gotta catch them before they hit the ground...

From Captain Marvel: "The Engine of Doom" by Bill Parker and C.C. Beck, Whiz Comics #12 (January 1941)

...and sometimes, you have to provoke the fall. Heh. "Gnatzis". Nice.
