On 7 September 2011, the United Nations Postal Administration (UNPA) will issue a set of 12 stamps depicting endangered species.
These will be the nineteenth set of stamps in UNPA's multi-year 'Endangered Species' series. The series was launched on 3 March 1993 to highlight the need for the protection of endangered species throughout the world. This year the endangered species feature endangered birds.
UNPA will issue three miniature sheets of 16 stamps, one sheet in each of the three currencies. Four different endangered species will be illustrated on each sheet; hence, 12 species will be covered.
The stamps were designed by Wendy Wray (USA).
