As revealed by ClaretandHugh last week the Commemorative Kit was inspired by one of the very first shirts to be worn by Thames Ironworks FC in 1897.
Featuring a navy blue design with Union Jack badge, the kit represents the ship builders who founded the Club. Because the third kit does not have a West Ham crest it is referred to as a Commemorative shirt and cannot be used for competitive matches, so the Juventus match will be the only game it is used for.
