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 grade 9.0 (VERY FINE/NEAR 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 causes reflection.
