Mighty Avengers #1 Retailer Incentive Variant CGC 9.8 Signature Series comic book, which has been signed by Brian Michael Bendis the series writer (Ultimate Spider-man, New Avengers), and signed by Frank Cho, the cover artist!
Retailers had to order 100 copies of the standard comic to get just one of these variant comics. This cover connects to the retailer variant edition of New Avengers #27.
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 comics web-site.
There are no cracks on the case. Any glare is just the scanner on the CGC case, which can cause reflection.
