Envelope drawn by Heleen (the Netherlands), that this gentle pigeon brought smoothly to my mailbox.
Europa Stamps are special stamps issued by European postal administrations/enterprises under the aegis of PostEurop. Since 1993, there is a common theme. In 2016, the theme was Ecology in Europe: Think Green. But in order to celebrate Europa stamps 60th anniversary (1956-2016), all the countries issued the same design.
Despite of all these countries participating in 2016, I had received only the Italian. So I was happy to get another one!
