Researched and designed by Kate Willaert at the behest of HalloweenCostues.com, what follows is perhaps the most comprehensive cataloguing of the Superman emblem variations that we've ever seen, and certainly the best Photoshopped. Placing the numerous emblems on photorealistic models of Clark Kent tearing his shirt open, Willaert explains the differences from the earliest Superman design by co-creator Joe Shuster to the latest refit created for the Man of Steelfilm, going into great detail about shapes, serifs and materials. This is superhero comics so doubtlessly she's missed a few that ComicsAlliance readers will be eager to point out in the comments below, but this is nevertheless a marvelous resource (for cosplayers in particular?) and tribute to American comics' most enduring emblem.
