Doug: Back in the Golden Age comic covers seemed largely to be used for two main purposes: patriotic propaganda and (especially in the case of DC) light-hearted humor. As comics segued to the Silver Age, covers took on more of a selling-point role, often showcasing events that would take place within the pages of the magazine. Of course, sometimes the covers sported teasers that didn't really happen -- this was also true more of DC than of Marvel. Now, however, comic covers are often merely splash pages -- material that might be better suited to posters or prints.
Doug: So what's your take on it? Do you hold particular covers as favorites that stand out in your mind? Are there those that draw your ire? Leave a comment, and thanks for your consideration of this topic!
