Ah that's a shame. Fortunately I had my old man with me to encourage me to go up to him as I would have been too shy too. Just can't remember if he signed my jersey, or my tigers hat (would help if I could find that too).
I've just found a jersey of mine from around 1991 with a signature on the back. I'm pretty sure it was Laurie Nichols who signed it, at a game at North Sydney Oval, but I was only ~6 years old so don't trust my memory. Does anyone recognise this signature? Cheers
