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 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 mint stamps will be available in selling units of a full sheet of 16 stamps or a single unit of a se-tenant block of four stamps.
