From target balls to the “smiley” badge, Marching on Together to sock tags, has anyone had a bigger, more lasting effect on Leeds United fan culture as Paul Trevillion. His contributions at a time when Leeds were at their most prominent have had an indelible effect on the club and helped to change the image of English football as a whole. The recognition that much more could be done to engage with Leeds’ ever loyal fan base and the creation of the iconic smiley badge in order to appeal to a wider audience beyond that of West Yorkshire, was a marketing stratagem way ahead of it’s time. His friendship with Don Revie shaped some of the most celebrated moments in Leeds United’s history and changed English football forever. Football has never looked back.
