Have you ever seen sheep grazing in Prospect Park? You haven't! Because it happened before you were born. Click through for a look at Brooklyn like you've never seen it before, because unless you're a time traveler, you likely weren't around yet—from Fort Greene in 1887 to a snowy commute over the Brooklyn Bridge in 1888 to the NYPD patrolling in the early 1900s. Okay fine, you may have been alive that time the evil scientist used Brooklyn cats for psychology studies, and when the Brooklyn Dodgers got naked for the LIFE cameras, but at least that latter moment in time is worth revisiting.
