Chew #19 Glow In The Dark Convention Variant CGC 9.8 Signature Series comic book from Image Comics, which is signed by John Layman and Rob Guillory, who has added a nice piece of original artwork to the cover in the form of a Agent Mason Savoy head sketch.
It is very hard to get in CGC Signature Series, particularly with a sketch, as the creators make infrequent appearances at US Conventions. CGC also now require that multiple signature books can only be done at the same show or event.
It has been professionally graded by CGC, the largest independent comic grading company in the world, and slabbed in a sealed protective case.
The grade is guaranteed to be high investment grade 9.8 (NEAR MINT/MINT) and this is a yellow label CGC Signature Series, which means that an authorised CGC representative witnessed the signings & artwork being created and this also acts as a Certificate Of Authenticity. As soon as the comic is signed, it is removed by a CGC authorised party and submitted straight to CGC for grading and encapsulation, guaranteeing the authenticity of the signatures and the artwork.
You can check the validity of this item and the signatures & artwork by entering the 10 digit number on the label at the CGC web-site at www.cgccomics.com
There are no cracks on the case. Any glare in the image is just the scanner on the CGC case, which can cause reflection.
