I am selling of portions of my personal collection.  You will receive (1) one  stamp.  Booklet singles Scott 2528 29 cent flag over Olympic rings stamp. These stamps were issued by the United States Postal Service in booklet format in 1990-1991. They come in mint never hinged quality and are ungraded.  There is no certification for these stamps, but they are highly collectible. They would make a great addition to any stamp collection.
