During the Cold War, Voice of America (VOA) broadcast mostly radio programs. Most of the radio transmissions were delivered through shortwave. VOA would send out QSL cards as a written confirmation of reception to those listeners who requested them by letter. The 1978 QSL card from VOA was a post card with pictures of San Francisco, the White House and the Statue of Liberty.
