I have a poster celebrating Geelongs record breaking score over the then Brisbane Lions. the poster as been signed by the likes of Ablett, Couch Bairstow, Hocking, Malcolm Blight among others. I bought the poster at Kardinia Park a couple of weeks after their victory and got it signed by the players at training the next week. It bears 11 signaures in total. Any ideas how much i could get for this piece of history?
