Amazing Spider-man #538 Retail Variant CGC 9.8 Signature Series comic book, from Marvel Comics, which has been signed by Clayton Crain, the cover artist!!
Retailers had to order 50 copies of the standard comic from Marvel Comics to get just one copy of this Amazing Spider-man #538 retailer incentive variant comic book, with a spoiler cover of Aunt May being shot.
It has been professionally graded by CGC, the largest independent comic grading company in the world, and slabbed in a sealed tamper proof protective case.
The comic grade is guaranteed to be high investment grade 9.8 (NM/MINT) and this is a yellow label CGC signature series, which means that an authorised CGC representative witnessed the signing and this also acts as a Certificate Of Authenticity. CGC remove the comic as soon as it is signed and ship it to their facility in Florida, to ensure that the signature is authentic.
You can check the validity of this item and the signature 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. The glare is just the reflection of the scanner on the CGC outer casing.
