In a day and age where sex is literally at our fingertips, where we can see x-rated pictures and films in the privacy of our own bedrooms (or even bathrooms), it’s hard to imagine that at one point in time, people had to venture out in public in order to see porn. They had to be seen entering an “adult” theatre, purchase a ticket, and sit in a room full of jerk-offs in order to see a porn flick. The x-rated film industry had to create enticing posters to lure viewers into said theatre, to make them want to risk someone they knew from work or school or church seeing them walk into one of these houses of ill repute. While porn flicks today have names like “Butt Job 7” or “Only Teen Anal 18,” the adult film industry had to be more creative in their presentation of x-rated films half a century ago. Here’s a collection of pretty hilarious vintage adult movie posters that may have gotten your dad or grandpa excited enough to go to the movies by himself. And be thankful for Tumblr.
