The product is a full sheet of 50 unused 1951 United Nations first issue stamps featuring the United Nations Headquarters in New York. These mint never hinged stamps are red in color, have a denomination of 1.5 cents, and are from the United States. The stamps commemorate the establishment of the United Nations and are a collectible piece of history from the early years of the organization. The cancellation type indicates the first day of issue, adding to the rarity and value of the stamps for collectors interested in United Nations memorabilia. Uncut complete sheet of 50. I do not know grading but they have been stored and look very good. There is a little curling on a corner area as seen. Face value is 75 cents.
