These are marked First Day Issue, cachet envelopes that were part of the Servicemen Series. This envelope was made to accompany the two stamps honoring Servicemen in connection with the 50th anniversary of the founding of the Disabled Veterans of America and those who were KIA, POW, or MIA. A very rare envelope. All are in very good condition. 6 1/2" X 3 5/8". Three red, two blue, and one black ink. Great collectibles, but they would make a special envelope for an old fashion mailed letter to your favorite vet. All sold together.
