I didn't know until reading Zac Hample's book that they actually 'game used' the specially marked balls for the WS/ Div series etc - although it's obvious now, D'oh!
But anyway in case you didn't too here's a link to them and how you can get one (other than ebay) if your team has done something special recently and you want a memento.
There's orange balls in the museum - remember orange footballs for the snow?
