To mark the "50 years of the WWF" anniversary Philatelie Liechtenstein is bringing out the issue entitled "Endangered bird species in Liechtenstein". It has been created by the Liechtenstein artist Jacques Sonderer and depicts on each of eight individual stamps (face value CHF 1.00) in a stylized natural environment a bird species endangered in Liechtenstein.
As well as the bird species threatened with extinction in Liechtenstein such as the nightingale (Luscinia megarhynchos) and wryneck (Jynx torquilla) the set illustrates the seriously endangered hobby (Falco subbuteo), the common redstart (Phoenicurus phoenicurus), the pygmy owl (Glaucidium passerinum), the red-backed shrike (Lanius collurio), the golden oriole (Oriolus oriolus) and the whinchat (Saxicola rubetra).
The issue is being produced as an eight-stamp se-tenant sheetlet in which all eight face designs feature in a coherent pictorial composition. The individual stamps are hexagonal and self-adhesive. The WWF panda logo is moreover printed on each stamp.
