The Walking Dead #100 Escape Variant CGC 9.8 Signature Series comic from Image Comics, which is signed by Robert Kirkman, creator & writer of the Walking Dead comics & TV Series, and long term Walking Dead series artist, Charlie Adlard, who has added a Zombie head sketch onto the cover!
It is particularly hard to get a sketched version like this in CGC Signature Series, as Charlie is based in the UK and does not regularly appear at US Conventions.
Only 2 other similar examples have ever sold, one for $393 in 2015 and the other for $400 in 2013.
It has been professionally graded by CGC and slabbed in a sealed protective case. The grade is guaranteed to be high investment grade 9.8 (NEAR MINT/MINT), which is the highest grade currently achieved on the CGC census.
It is also a yellow label CGC Signature Series, which means that an authorised CGC representative witnessed the signings and sketching and this also acts as a Certificate Of Authenticity.
There are no cracks on the case.
