@irishx: Very sorry to hear that, I'm currently attempting to track down an email address or something to get in contact with the artist to see what is going on. The optimistic part of me wants to think that I will get it one day but his deadlines and stuff got in the way but the realist in me knows I was burned and will no longer be as courteous to them, in a situation like this.
So Mann did not ask you to leave an address or anything? That is pretty crappy of him, to burn a fan like that, I mean sketches and stuff are not cheap and you think an artist would want to go out of there way to appease there fans so they will come back for more.
As for Celebrity stories I have heard some horror stories about Stan Lee but I have met him twice and the first time he went out of his way to talk to me for a few minutes, and was very kind.
@voodoopenguin: Sure it was Ken Lashely, and truthfully I do not really want to support any of his work now which sucks because he is now the artist on Secret Six a book I have waited for.
