Following last week's announcement of 12 Gold Sponsor comics, today marks the reveal of all 35 Silver Sponsor titles for Free Comic Book Day 2012. The comics will be available at participating retailers on May 5, though availability will vary from store to store. The Silver books are suitably heavy on all-ages fare and gateway stories this year, with Atomic Robo, Spider-Man: Season One, Voltron Force, Sonic the Hedgehog, Top Shelf Kids Club, Valiant's kick-off comic, Cartoon Network's DC Nation shows and more on the list. See this year's Silver titles after the jump.
