This variant was another comic that was only available to retailers who attended the Diamond Retailer Summit in Las Vegas in May 2014.
The comic was written by Robert Kirkman with art by Charlie Adlard & Stefano Gaudian (cover by Adlard) and key comments noted as "1st appearance of Magna, Luke, Kelly,
Connie, Yumiko, Annie & Siddiq. 1st appearance & death of Bernie".
CBCS, PGX and CGC all note this variant as the Diamond Retail Summit Edition and the cover sports the diamond summit logo just underneath the title to the right.
In mid February 2014, CGC have recorded 102 gradings of the comic with well over 50% at CGC 9.8. For a high grade copy you can expect to pay anything from $90 to $225 for
a CGC or CBCS graded copy.
