Celtic's training shirt for the 2013/14 season, made by Nike. Away from matchday attention, this piece belonged to the everyday rhythm of sessions at Lennoxtown during a period of squad transition. The horizontal green and white stripes reinterpret the vertical hoops that have defined Celtic's identity since 1903, a subtle but deliberate nod to the club's visual language, adapted for a training context. For collectors, its appeal lies precisely in that ordinariness: a behind-the-scenes object that captures the club's daily life rather than its headline moments.
