The game was played on Saturday 25th April 1914 and the club will mark it for the last home game of this season against Ipswich by playing in a specially commissioned shirt.
That shirt is a modern replica of the 1914 shirt bearing the royal crest. We were able to wear it in 1914 after the privilege was bestowed on us in October 1886 by Prince Albert Victor on the occasion of him visiting Burnley to open the Victoria Hospital. During his visit he took in the game between Burnley and Bolton, thus becoming the first Royal to attend a game of professional football.
But the centenary will be marked, not only by the wearing of that shirt, but with an exhibition in the Long Gallery at Towneley Hall. The official opening is this Sunday and subsequently will be open to the public from Monday for the remainder of the month.
The shirt to be worn at the end of the month will be on display but probably the most special of shirts on view will be that worn 100 years ago on the occasion of the final by goalscorer Freeman. It was recently bought at auction by co-chairman Mike Garlick.
Freeman's medal is there, as are those of Tom Bamford and Eddie Mosscrop. Mosscrop's shirt and the international cap he won in 1914 are also on view.
There's much more including a copy of the match programme, press cuttings, the menu for the dinner hosted in the Connaught Rooms by MP Mr Philip Morrell and Lady Ottoline Morrell.
Mike Smith's excellent book on our FA Cup triumph, entitled The Road to Glory, will be available for purchase in the Long Gallery.
Admission to the exhibition is free to all residents of Burnley and to Burnley FC season ticket holders. Otherwise admission is £4, but free to students and under-16s.
The shirt to be worn for the Ipswich game will bear a label naming the manager of the time - John Haworth - and the team that brought glory to Burnley FC. That team was: Sewell, Bamford, Taylor, Halley, Boyle, Watson, Nesbitt, Lindley, Freeman, Hodgson and Mosscrop.
Clarets Mad will have photographs from the exhibition on Monday.
