Postage stamps are being issued to celebrate World Radio Day which takes place 13 February 2013.

World Radio Day is observed on 13 February 2013, which marks the day when the United Nations Radio was launched in 1946. Since its establishment, UN Radio has used its multilingual programmes carried by media outlets around the globe to tell the story of the international community’s efforts to meet the challenges of building a better world.

The United Nations Postal Administration (UNPA) will issue a series of stamps depicting scenes from the history of the United Nations Radio.
