As Michael Ryan reminds us over at Palaeoblog, Saturday, May 7 is Free Comic Book Day. So head on to your local comic shop and pick up some great specially-made freebie editions like Flight, Superior Showcase #0, Bone Sharps, Cowboys, & Thunder Lizards, Star Wars: Revenge of the Sith, The Batman Strikes and Walt Disney's Uncle Scrooge.
Sadly, Free Comic Book Day is not a day where you can venture into a comic book shop, pick out any book, and walk out without paying, but rather a great way to introduce new readers (and remind previous ones) to the world of comic books and graphic novels. Publishers produce special editions to give away at local comic shops to support the endeavor and there are often some great little gems distributed.
You can read more about it on the official website.
You can also use the Store Locator to find a shop near you.
