Don Revie, the Leeds United manager first picked up on the potential of unique kit design when he signed a deal with Admiral to produce the first strips bearing manufacturers logos to be sold as replica wear for the fans. Umbro, Bukta and Adidas were not far behind and soon their logos were all over football shirts. Commercialisation was beginning to find its way into football. Even at the Oval the trend was apparent when towards the end of the 1976/77 season Glentoran began to appear in a revamped version of the previous kit. The colouring sequence in the middle three stripes was different, and now the Umbro diamond also appeared as sleeve trim. Players had an option of short or long sleeved shirts and for the first time Glentoran supporters were able to buy replica jerseys. Umbro could not have picked a better time to employ this strategy as Glentoran would lift the Irish League, Ulster Cup and Gold Cup in 1977 in this shirt and the Gold and County Antrim Shield in 1977/78 with Arthur Stewart at the helm.
When Glentoran arrived in Reykjavik for the first round first leg European Cup tie in they were given a very special gift. Halldor Einarsson one of the Valur players owned a sports company in the Icelandic capital called Henson Sports. As a gesture he made both Valur and Glentoran special “one off” playing strips for the game. Glentoran’s shirt seen above was worn with white shorts and red socks and carried red numbering on the reverse. Halldor is still in contact with Philip Stevenson a member of the Glenmtoran Supporters Committee (1923) and has paid host to Glentoran supporters during a recent visit to Reykjavik. One of the shirts can still be seen in the clubroons of Ballymacarrett Glentoran Supporters Club. The game was played at the Laugardalsvoller Stadium in Reykjavik. Valur resorted to pushing, ankle tapping and shirt pulling in an attempt to incite the Glens. Despite being warned not to get involved Alex Robson was lucky to stay on the pitch after an off the ball incident with Alti Edvaldsson who ended up clutching his face and writhing in agony on the ground. Glentoran lost the away leg 1-0 but overturned the deficit in Belfast.
