Avengers #1 Blank Sketch Variant (2010) CGC 9.8 Signature Series comic book, from Marvel Comics, which has been signed by artist Clay Mann, who has sketched and inked a full wraparound original artwork cover of Captain America battling the Red Skull!

This is a piece of original sketched and inked artwork by a professional comics artist, not a pre-printed cover. Clay Mann has worked on a range of Marvel titles including Daredevil, Thor and X-Men.

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 signature.

The authenticity of this item can also be validated by entering the 10 digit serial number of the CGC yellow label into the Certification Lookup search box at www.cgccomics.com.

There are no cracks on the case. Any glare is just the reflection of the scanner on the outer CGC sealed case.
