The photo above ran in the August 6, 1970 Daily Courier (Connellsville, PA). The last sentence of the picture's caption appears to believe that the telephone was "discovered" rather than invented. Start digging and you may discover some brand new technology, in your own backyard!

The exhibit is sponsored by Bell Telephone and is entitled "Yesterday, Today and Tomorrow". It shows the progress made in communications since the phone was first discovered.
