The name of the winning team is engraved on the silver band around the base as soon as the final has finished, in order to be ready in time for the presentation ceremony. This means the engraver has just five minutes to perform a task which would take twenty under normal conditions, although time is saved by engraving the year on during the match, and sketching the presumed winner. During the final, the trophy wears is decorated with ribbons in the colours of both finalists, with the loser's ribbons being removed at the end of the game. Traditionally, at Wembley finals, the presentation is made at the Royal Box, with players, led by the captain, mounting a staircase to a gangway in front of the box and returning by a second staircase on the other side of the box. At Cardiff the presentation was made on a podium on the pitch.
When does the engraving take place?
as soon as the final has finished, in order to be ready in time for the presentation ceremony.
