If anyone is mailing you something from Australia, check the stamp. They may be mailing you a tiny picture of P&O's Pacific Explorer.
The Australian postage stamp is actually celebrating Norfolk Island which is a popular cruise destination, but it prominently features the P&O Australia ship, which is a regular visitor there.
Details appear in the September 17 issue of Cruise News Daily.
