Telecom Eireann Callcards - mint

"The now defunct callcard released in 1992 to mark 400 years of Trinity College. This callcard still has the full 50 units credit on it, and is classed as mint. One better, this 2nd callcard is still in its wrapper and has its full 10 units credit on it. I'm not sure what the coded message on this one was in reference to! "
