bigbobs has a old t shirt which may or may not have been used by Nasser, but it is NOT sports memorabilia, its an old t shirt....
having a hockey jersey that has been worn in a game (hopefully winning) counts as sports memorabilia
having a trophy won by a certain team or person counts as sports memorabilia
having a MR O trophy or medal counts
having boots or hockey skates worn by a certain player in a game counts...
HAVING A T SHIRT THAT NASSER WORE (AND HE MAY HAVE TRAINED IN IT) IS JUST AN OLD T SHIRT..
bigbobs gets my vote for sure
