What's your rarest Beastie Boys item?

Is it a rare vinyl? A piece of memorabilia from a show? An autographed object from all three Boys? Let's hear what you got! I'll start. I have Mike D's drumsticks from the 5/7/99 Wembley Arena show in London. I had VIP tickets, and at the end of the show, Mike came over and threw his drumsticks over to me. Pretty cool moment. Curious what other fans have.
