Vintage Bophuthatswana World Title Fight Commemorative Postage Stamp Card.
These two postage stamps are issued 2 June 1979, to commemorate the historic meeting between two of the world's best boxers, Kallie Knoetze of South Africa and John Tate of the United States of America, at the Mmabatho Stadium. It is an eliminating contest to determine which of the two will be the rightful contender for a world championship bout that will be recognized as such by the World Boxing Association.
