I need help finding a television program. I believe it was like "In Search Of" which dealt with real life mysteries in a scientific format. It was a television show on time travel. The show was on years ago, when I was young. I am guessing between 1972 to 1989.
Here is the key: there was a photograph of the Gettysburg Address in the television program. The commentator noted that the child in the centre of the photo was a time traveller, but his identity would not be revealed. This was said as a statement of fact. The program could have been on TV only that one time, because of this statement.
I guess I would need a list of all kinds of television programs from that time period. Any help would be appreciated.
