Its nice to meet the creative teams behind your favourite comic books, gaining a signature or sketch along the way.
I went a bit mad for it some years ago, presenting Simon Furman entire runs of stuff to sign (gawd bless him)!
I would assume any signatures you have on the comics would be respective of the creative team working on that particular book?
I have found some info on each book below which may be of help...
