Ok, they’re just being jerks on the cover of World’s Finest 28 (May/June 1947).
Lex Luthor gets his first World’s Finest story, by Cameron, Yarborough and Kaye. It’s not the greatest. Often the Superman and Batman stories than ran in this book were the weaker ones. It’s mostly a set-up for the final couple of pages with the giant Superman statue.
Luthor creates a machine that brings statues to life. At the start, this is just used for robberies, but the story builds up to him animating the big Superman statue.
Superman gets out of it fairly easily, so the end is a bit of a let-down.
