The Strangers’ Guides were like Yelp in the 1800s, advising visitors to TwistedPhilly where to go, and in some cases where not to go. One little Strangers’ Guide is a veritable map of Victorian whorehouses from 1848. This thing reads like a tame version of Playboy stories, while ad the same time admonishing young men for even considering visiting a house of ill repute, which the author obviously did or he’d have no idea about where to visit and where to avoid.
