Batman in Indianapolis

52-year-old Kevin Silva from Indianapolis likes Batman, a lot.

This is his stash of memorabilia related to the caped crusader.

He calls it "the bat-cave," and it comprises more than 2,500 figurines, lunch boxes, capes and utility belts, among many other things.

Silva says he started collecting batman-related items after getting hooked on the 1960's show as a kid, and now it's officially the biggest accumulation of batman collectibles in the world.

Silva said he's had the collection appraised at $100,000, which is way more, he says, than he spent collecting it all over the years.
