The Abbey-Principality has issued its first stamps. The First Class issue in azure blue depicts the achievement of arms of the Abbey-Principality as well as the seal of San Luigi and the cypher of Prince-Abbot Edmond III.

For a government-in-exile such as San Luigi, stamps are used as carriage labels, similar to the issues made over the years by the islands of Lundy and Herm. They are used on official letters affixed and cancelled by the Chancellery on the bottom left corner of the envelope, while the national postage of the country concerned is affixed to the top right.

The first issue of stamps marks the 130th anniversary of the Abbey-Principality, which falls on the 25th of this month.
