What do you find in the Rock and Roll Hall of Fame?

I was wondering what you would find in the rock and roll hall of fame? would it be like Elvis' middle school report card? Madonna's bib when she was younger? Random stuff like that? or do they have things like Jimi Hendrix's guitar and pick and stuff like that? I'm doing a theme for school and I need to know how to decorate it as a rock and roll hall of fame. ideas?|||you'll find things like outfits they wore during a concert of in a music video. the real things. and also guitars theyve used, guitars theyve thrown ou tin the crowds and got broken. they've got a HUGE room dedicated to the clash. throughout the Hall of Fame they have videos of live concert recordings. sometimes theres random things like diaries, or lyrics that were never published or whatever. But its really reall fancy too.|||Though there are many items by rock greats... there are also alot of things and displays of people/groups who have NOTHING to do with Rock %26amp; Roll
