On 6 September 2007, the United Nations Postal Administration (UNPA) and the Universal Postal Union (UPU) will issue commemorative stamps on the theme "Humanitarian Mail". UNPA will issue three stamps (in a mini-sheet format) and UPU will issue a stamp in Swiss denomination. A special joint silk cover will also be released on the same day.
Over the years, the general mail and the mailing of parcels have been used for humanitarian uses throughout the world to provide support for the needy and to raise funds for all kinds of humanitarian needs. To commemorate the use of mail for humanitarian purposes, UPU and UNPA have decided to commemorate and acknowledge mail used for humanitarian causes through this joint stamp issue.
