Our Local Stereoscopic Museum
Meadville was the home to the Keystone View Company. You know...the company that made the vast majority of the 3D stereo cards for the old Holmes stereoscopes. There is a nifty little museum in town where you can go to check out their collection! Coincidentally, this place is literally just down the hill from my house.
This is a 3d image. You will need your red/cyan 3d glasses to get the effect. Remember that the red lens goes over the left eye!
