Here's a classic example of WHY the cover of a comic book should ALWAYS reflect the story inside. Here the cover shows Green Hornet and Kato busting some counterfeiters ("We'll teach you conterfeiters that you can't get away with crime!"). HOWEVER, read the text in the lower left-hand corner.
"Marijuana Racket"? Just WHAT are these guys counterfeiting? Talk about confusing your readers.
"We'll teach you not to put fake stuff on the streets! What the heck is that, anyway? Marjoram? No -- oregano? Oregano! That's IT -- we're gonna make honest crooks out of you, by gosh!"
