This is a beautiful sheet of 16 United Nations stamps issued in 2008 in Geneva, featuring endangered species. The stamps are of high quality, and although they have been previously used, they are still in excellent condition. The colorful design depicts different species of endangered animals, and the cancellation type is First Day of Issue. This sheet comes on a large First Day Cover, making it a great addition to any collection. The stamps are ungraded and uncertified, but their unique design and important topic make them a must-have for any stamp enthusiast interested in protecting endangered species.
