The Christmas stamps 2010 have been designed with a graphic technique called copper edging. The design is based on the Advent wreath. The main theme is the circular form in the colours of winter, the circle also symbolizing the earth, its seasons and infinity. On one stamp the circle is covered with snow crystals, on the other with snow flakes. Interwoven with the theme on both stamps are the Icelandic birds of winter, the snow bunting (Plectrophenax nivalis).
