A set of 4 United Nations "Endangered Species" commemorative stamp collection booklets purchased during a trip to the United States approximately 30 years ago (1993-1996 editions). All stamps are unused and housed in the booklets, allowing you to enjoy them alongside beautiful illustrations of animals and plants. ☆Recommended Points☆ ・A rare opportunity to acquire a 4-year set! ・More economical as a set than buying individually ・Perfect not only for your own collection, but also as a gift for animal lovers♪ ・Framing them will make them a great interior decoration Although there is some age-related deterioration due to home storage, the overall condition is good. This is a recommended item for stamp collectors and those who love animals and nature.
