On Saturday I got two postcards: one from the Åland Islands and one from Germany.
The card from the Åland Islands shows the fauna of the islands. On Åland live around 25 mammal species and around 130 bird species breed there. Apart from the game nearly all animals living on the islands are under conservation.
With a related stamp:
sepac (issued 20-08-2013)
The stamp shows a Peacock butterfly.
The stamp uses modern Augmented Reality technology and if you scan it with the "Sepac App" it creates a three-dimensional picture of Åland (see pictures below).
with a special postmark about World Post Day
Thank You very much Liisa!
