2003 Spanish constructors trophy...error?

[pipe'n'slippers]

I am currently enjoying a visit to & around Maranello, including (of course) the Ferrari museum. In the Hall of Victories there are various Constructors trophies. I noticed that the 2003 Spanish trophy, shaped like a steering wheel, has the plaque recording the event on upside down. Was this a simple mistake or was there a reason for this?
