Imagine our surprise one afternoon as we sauntered through our neighborhood, full of shoppers and families, to come upon — the Leather Archives and Museum. Indeed, right on the south edge of Rogers Park, a veritable treasure trove of fetish history on display. And they just started a new exhibit all about masks. And we’re not talkin’ cute Halloween masks. Watch this homey video and then check the place out, if you dare, at 6418 N. Greenview Ave. (773-761-9200).
