A durable sticker for the car, computer or suitcase. It is nice to see one on the back of a car when you are out of port. LYT is the three letter code for Lyttelton, and is often stamped on goods coming in through the port. Not to be confused with LYTT, which is the local abbreviation for Lyttelton from way back. The 3 letter LYT sticker is also a play on international 3 letter country codes.
