Forbidden erotica:

This collection presents the finest highlights from the collection of New Yorker Mark Rotenberg, who began collecting antique smut after finding a stash of vintage erotic pictures in a Brooklyn dumpster and now owns a 95,000 strong collection of archive pornography dating from between 1860 and 1960. Flick through these pages and witness the fitness of our forebears as they romp, cavort, and frolic with unabashed energy and glee.
