Here is the best explanation I could find of how to play Ghost and Super Ghost. From some other photos I've seen, this came with letters and score cards.
There is wealth of information about Dr. Bergen Evans (above). He was a professor of English at Northwestern University. He hosted another game show called Down You Go, as well as two other shows called Of Many Things and The Last Word. He also wrote several popular reference books and newspaper columns, many aimed at increasing peoples vocabulary. While you can find information about Dr. Evans, two other things are hard too find: a photo of Bergen Evans with out a watermark and video of his TV shows. I managed to swipe this photo and enlarge it. Archive-dot-org has one of the only known copies of Down You Go in existence.
Ghost has gone modern too. You can find Ghost game apps on Google Play and online.
