Over the last couple of weeks, I read Challengers of the Unknown, all four Showcase appearances and #1-9 of their own mag. Kirby drew all of these issues, and Wood inked most of them, so they're awfully pretty.
They're also good evidence of just what Stan Lee brought to their pairings: personality. The Challengers' dialogue balloons are virtually interchangeable, their private lives are non-existent, and their backgrounds are blank. Kirby's amazing creativity is on display, but without actual characters paired with that proliferation of ideas, reading them becomes surprisingly like an obligation or a chore instead of a joy.
