Tomorrow marks the tenth anniversary of Free Comic Book Day, an annual event that delivers precisely what it promises. Retailers across the U.S. will be offering specially printed copies of comic books, along with discounts on back-issues and other items; and while each shop determines its own policies as to whether people can collect multiple books, anybody who comes in is entitled to at least one freebie.

Celebrated on the first Saturday of May each year, Free Comic Book Day has usually been tied to the release of a big studio film release of a superhero movie, and this year The Avengers is the timely blockbuster. The freebie comics being given away this year feature an Avengers title, along with installments from other series ranging from Spiderman to Peanuts.  The give-away comics are listed here, and if they suit your comic tastes, you can find a retailer participating in Free Comic Book Day using their store locator.
