Amazing Spider-man #648 Blank Sketch Variant CGC 9.8 Signature Series Signed comic book from Marvel Comics, which is signed by the following:
Stan Lee - the late co-creator and the original writer of the Amazing Spider-man in 1962.
Dan Slott - long term series writer.
Humberto Ramos - series artist, who has sketched and inked original artwork to the front cover in the form of a detailed Green Goblin sketch. This is original art by a professional Marvel Comics artist, not a pre-printed cover.
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 signing and sketching 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 original artwork.
You can check the validity of this item and the signatures and sketch by entering the 10 digit number on the label at the CGC web-site.
There are no cracks on the case. Any glare is just the scanner on the CGC case, which can cause reflection.
