Before we get into those creepy stereoview cards below…. what the hell is a stereoview anyways?! Basically, a stereoview is two pictures of the same scene, but shot at slightly different angels. When the images are viewed side by side in a stereoscope, you would get a 3D effect. An example of this is flickering the right and left sides of the photo. Like the two below.
Now here are some creepy ones from the early 1920’s titled, “The Goblins will get you if you don’t watch out“. Just imagine viewing these through a stereoscope as a kid….. chills! You can also use these today if you don’t ever want you children to sleep again.
