In late 1966 plans were rolled out to introduce ''Association Football” to the United States. An invitation was offered to the Irish League to send a side to represent Northern Ireland in the new set up the following May. Linfield rejected the proposal as it meant that some matches may have had to have been played on a Sunday. Glentoran however immediately agreed. Before embarking on the 12 match, two month coast to coast tour of the States, the small matter of playing uniform had to be resolved. The Glens unveiled this shirt as the official playing strip for the duration of the tournament which saw the East Belfast side based in Detroit. As it turned out this kit was never worn and mysteriously disappeared.
