Actually, yes I do. My copy of "A Kiss in Time" is autographed by Alex Flinn. There just happened to be an autographed copy at my local Barnes and Noble :)

I forgot to answer my own question ! I have an autographed copy of State Of Fear by Michael Crichton ( from a signing in San Francisco ) and Pete Townshend signed Horses Neck ( a book he wrote in 1985).

Tim Burton signed my 'The Art of Tim Burton' and 'Tim Burton: the Exhibition Catalogue'.

I took a plane to Melbourne, got up at 4am, waited outside for 7 and a half hours in the middle of winter, and spent over $100 for the signing token (without it, you weren't allowed to get his autograph), just to meet him! XD Best day of my freakin' life!!!

yyyuuup! "Shock" by Robin Cook is signed by her (author) nd Brandon Mull signed my copy of "The Candy Shop War"
