i have a museums worth...

a couple t-shirts
some posters
tons of magazine pictures that used to be taped all over my closet doors back in the 80's
at least a dozen buttons from back in the day (but not the rude boy one )
tour books
ticket stubs ( I even saved the parking ticket stub from one of the concerts)
dvds and vhs tapes, including stuff I recorded from some of his many tv appearances
thats all I can think of right now I'm sure there's more
