As part of its "We Can Be Heroes" campaign to fight hunger in the Horn of Africa, DC Entertainment has kicked off an effort on Indiegogo to raise $50,000 in donations in exchange for "epic Batman stuff."

Perks range from five Batman comic digital downloads (for a $10 contribution) to an exclusive Batman: Earth One lithograph by Gary Frank ($50) to a copy of the Injustice: Gods Among Us video game signed by creator Ed Boon ($250) to a cameo in the second volume of Batman: Earth One ($5,000). The copies of Batman and Robin #18 signed by Peter J. Tomasi have already signed out. There are even more rewards on the Indiegogo page.

The Batman-themed fundraising effort ends May 17.
