About the item:  

Incredible Hulk #393, signed by hand by Ron Frenz (penciler) and Al Milgrom (inker) - they are the artists on the Famous Hulk battles... vs Thor pinup inside the issue.  It is also signed by Jim Starlin (artist - both pencils and inks - on the Hulk vs Thing pinup inside the issue) and authenticated by CGC with a grade of 9.6.  Giant anniversary issue, foil cover, and a Newsstand edition!  Please note, with Signature Series books a certified CGC witness actually observes the signing of the comic so there is no possibility of the real autograph being switched out with another.
