We all know someone who collects coins, PEZ dispensers or even pop culture memorabilia. But for some of New York City’s most fascinating collectors, their collections are less a hobby and more like an obsession. Sometimes it’s even a full-time job.

We spoke with everyone from a Troll doll collector (whose fetish objects of choice have gotten something of a bad rap in the last few years) to a guy who for some confounding reason amasses pizza boxes.
