The first Saturday in May marks the annual Free Comic Book Day in which comic book retailers all across North America (and even the world) offer select comic books for free.
One of the offerings this year will be a special edition of The World of Cars #1 from BOOM! Studios. In addition to Cars, BOOM! works hand in hand with Disney and Pixar to produce comics based on The Incredibles, Toy Story, Monsters, Inc., the Muppets and more.
