But what do we have here? Two triangular flower stamps with an earlier postmark, 12 March:

And the International Polar Year MS, with a 2 October 2008 postmark!

The Panadero stamp is postmarked 18 November 2007, and the shells block is also 2007


All with a regular postmark from the office of posting also dated 26 March.

Obviously the philatelic service has applied older stamps and cancelled them each with their relevant first day postmarks! I've never seen the like of it before, but I suppose it can't be the only one?
