Amazing Spider-man #640 Retailer Incentive Sketch Variant CGC 9.8 Signature Series comic book, from Marvel Comics, which has been signed by Stan "The Man" Lee, Marvel Comics legend and co-creator of the Amazing Spider-man, and signed by Joe Quesada - writer, cover artist and Marvel Editor In Chief!
Retailers had to order 100 copies of the standard comic to get just one of these rare sketch variant editions.
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 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.
You can check the validity of this item and the signatures 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.
