Meet Mark Flitman

Mark Flitman is not your ordinary collector. He does not accumulate items that revolve around a particular passion, as do most of the collections we have featured. Instead, Mark calls himself a "career collector," as his vast array of items come from his many years spent in the video game and toy industries. He will show Lisa everything from the 3D prototype for Nintendo's Game Boy, to the original style guides for "The Simpsons," to one of the only Elmo characters never released to public. Mark is joined by one of his daughters, Michelle, and pop culture and toy expert Joel Magee, who will appraise the entire collection. Joel will later offer to trade Mark not one but two rare items from his own collection in exchange for one of Mark's most unique possessions.
