After looking at hundreds of comic book covers, it becomes quickly apparent that not every cover is 100% original. Whether done intentionally or even underhandedly, there's something about uncovering these "swipes" that adds a new element of fun to reading and collecting comics. Taking a page from Marvel and DC's marketing book, Skullkickers decided to relaunch their book with a new issue #1 and an enticing title change. Issue #21 was renamed MIGHTY SKULLKICKERS and the numbering changed to #1. I think the plan worked, and sales increased - even though it was a noticeable swipe at the big two publishers.
