Estonia had planned to enter the Euro zone beginning of 2007. Due to a high inflation, this entry has been postponed until beginning of January 2008. Nevertheless, since the beginning of the year, the Estonian post is issuing stamps with a double face value : one in Kroon, the current currency of Estonia and one in Euro. Here are some examples of recent stamps issued by Estonia, that I received from a philatelic contact there.
This stamp has been issued the 1st of February 2006 and pictures an elk (Alces alces). The elk, also called moose in North America, is the largest member of the deer family (Cervidae).
This other stamp has been issued the 1st of June 2006 to commemorate the 60th anniversary of UNICEF.
