For the fans of the classic DC superheros, DC Comics has created a series they call 52. They are making the first five issues free as PDF downloads on UGO.com. The download links are at the bottom of the page so you can scroll down and avoid the annoying overlay ad that appears at the top of the page.
Mature readers will appreciate the free first issues from many of DC Comic's Vertigo series of dark and sometimes disturbing comic books.
