Also known as Stereographs or Stereoscopy are usually viewed in a Stereoscope. Very
popular during the Victorian Era and still in use today. I’m sure many of you have
seen them in use in period movies. One can also view them without a Stereoscope by
using the wall-eye method. Warning may cause eye strain.
Some people have a hard time with this method, so I’ve switched sides in the next
picture to provide the easier cross-eyed method. Try it out.
