vols autograph habits

[tricitiesvolsfan]

been seeing on ebay a lot of people selling ut mini helmets signed by the current players. in the description it says they either got them before the vol walk or after the game. does anybody have any good info on this? i am working on my sports room and have about 125 signed helmets of the former guys who played from the 1940's-1990's. i will get chip kell this weekend at the vol village. thanks for the help. mike
