The Rosa Parks Commemorative Stamp was released this month. This stamp is part of the Black Heritage Series which started in 1978. The first stamp released in 1978 in this series was for Harriet Tubman. You can read more about the celebration honoring Rosa Parks by the Postal Service by clicking this link.
Each fall the honoree for the next stamp is announced. Usually the stamp is available by the Postal Service for at least a year. That means just like coins you can usually get them directly from the US Mint or the US Postal Service. If your local Post Office does not have the stamp you can order them online from the Mint.So, with that in mind you can order your Rosa Parks Stamps and First Day Covers ( an envelope with the stamp and image) by clicking this link.
