Your favourite Autograph?

I have tons of autographs. Mostly hockey and sci fi / fantasy actors. As for hockey I have entire Panther team collections for years 96-2005 on t shirts and jerseys. Each from a different year. Other then that I would have to say my Gretzky autographed 8x 10. Also I got Petr Statsny's autograph and got a nice chat with him in Czech. He and I had a nice few minutes. I also have Denis Potvin's autograph. Sci fi wise you could say that William Shatner and Leonard Nimoy were coups . I also have a couple from the late Jimmy Doohan.
