Avenging Spider-man #1 Joe Quesada Retailer Incentive Sketch Variant CGC graded comic book from Marvel Comics. 

Retailers had to order 200 copies of the standard issue to get just one of these Quesda Sketch Variant editions, so what were the chances of it being investment grade 9.8 in a polybag???

It has been professionally graded by CGC, the largest independent comic grading company in the world, and slabbed in a sealed protective case. The CGC grading process also assesses the comic for numerous types of restoration and found none. 

You can check the validity of this item 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. Any glare is just the scanner on the CGC case, which can cause reflection.
