Occasional date stamps
All regional and local events can be further highlighted and commemorated – beyond standard activities – with commemorative postmarks. These are special postmarks designed to mark important anniversaries or local events. During the selected period, all mail sent through the local post office will be stamped with a date stamp designed specifically for the occasion.
