The Celtic 2013/14 home shirt, made by Nike, carries the vertical green and white hoops that have defined the club since its founding in 1888. Over more than a century, those stripes have remained remarkably consistent through changing kit manufacturers and shifting eras of the game. Nike's interpretation brings its own technical and visual language to the template while keeping the essential pattern intact. For a collector, this shirt represents one of the most immediately recognisable visual identities in European football, understated in concept, distinctive in practice.
