Worn by England U21 International keeper Mervyn Day, in the 1st Leg of the Final of the Anglo-Italian Cup Final vs A.C Fiorentina on Wednesday September 3rd 1975.
Played at The Stadio Communal in Florence, in front of 33.000 spectators.
West ham lost the both games 1-0, and Day made a blunder in this shirt.
The only goal of the game came from Guerini, who hit a low, and not a particularly hard shot from 20 yards.
Day went to his right to make a routine save, and unaccountably, let the ball go through hid hands.
Its not the biggest of finals, obviously, but West Ham haven't played in to many.
A great 43 year old shirt to add to the collection.
