Must ... have ... DRAMA!
Starman, as always, delivers. Dr. Doog, easily recognizable by his trademark Yellow Bathrobe of Doom, prepares to throttle up the old Ultra-Dynamo.
Even one such panel from the brilliant Jack Burnley can serve as a primer on Creating a Dramatic Comic Book Panel. Light from below and use chiaroscuro. Use severe changes in font size to impart power to phrases. Catch characters poised just on the verge of action. Mysterious machinery in the background is good, particularly if it has a hyperbolic name and unspecified powers. Proximity is frightening; always place evil nearby, such as in the next room.
But what really interests me in this panel is the use of the word "super power". It hasn't become one word yet, and it isn't being applied to a person's abilities. Still, it's the first use of that phrase I can remember (it's from April 1941); are there any earlier ones that you know of?
