Argentina and the United Kingdom first fought over the Falkland Islands (Islas Malvinas) using stamps. Argentina countered a 1933 Falkland Islands stamp celebrating the centennial of British Administration with a stamp proclaiming its dominion over the islands. In the 1980s both countries issued stamps showing historic maps as evidence of their territorial claims. The 1982 war brought bolder assertions: an Argentinian stamp overprinted with ?Las Malvinas Son Argentinas? (The Malvinas Are Argentine) shortly after its military occupation of the islands , and British stamps honoring the islands? ?liberation.?
