CNN - 52-year-old Kevin Silva from Indianapolis likes Batman.
This is his stash of memorabilia related to the caped crusader.
He calls it "The Batcave," 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.
"I've had people drop to their knees at display cases -- 'oh my God look at all this stuff!' This is the official certificate that the largest Batman memorabilia belongs to me," Kevin Silva, Batman enthusiast said.
Silva said he's had the collection appraised at $100,000.
Way more, he says, than he spent collecting it all over the years.
