Europa 2008 - The Letter (Bulgaria 2008)

Stamp Europa 2008 - The Letter it reflects the thematic directions:

Birds (Aves), a subgroup of Reptiles, are the last living examples of Dinosaurs. They are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds. Birds are the closest living relatives of crocodilians.

The European Conference of Postal and Telecommunications Administrations (CEPT) was established on June 26, 1959, as a coordinating body for European state telecommunications and postal organizations. The acronym comes from the French version of its name Conférence européenne des administrations des postes et des télécommunications.

The Europa postage stamp (also known as Europa - CEPT until 1992) is an annual joint issue of stamps with a common design or theme by postal administrations of member countries of the European Communities (1956-1959), the European Conference of Postal and Telecommunications Administrations (CEPT) from 1960 to 1992, and the PostEurop Association since 1993. Europe is the central theme. EUROPA stamps underlines cooperation in the posts domain, taking into account promotion of philately. They also build awareness of the common roots, culture and history of Europe and its common goals. As such, EUROPA stamp issues are among the most collected and most popular stamps in the world. Since the first issue in 1956, EUROPA stamps have been a tangible symbol of Europe’s desire for closer integration and cooperation.

Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). All animals are motile, meaning they can move spontaneously and independently, at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance.
