Robert Kirkman and Charlie Adlard walked out to loud applause at the opening of The Walking Dead 10th Anniversary Panel at New York Comic-Con 2013. The panel began with screen shots of the covers for their newest 12-issue story arc titled “All Out War.” Robert Kirkman went on to explain that the first issue in the series – number 115 – came out this past Wednesday. They had 352,000 copies printed and it sold out within the first few days, making it the highest selling single-issue comic so far. The second printing will have four issues.

Adlard, who has been drawing the series since the beginning of its run, did a special cover that included major scenes from the past 10 years. The panelists proceeded to show some artwork from the new issue, the first being a panel in which Rick is leading a small army – gun pointed forward – to fight adversary Negan. Adlard began to talk about the inking process saying, “In the past 20 years, I have never ever not inked myself. Stefano is the new inker – he is proving us right and doing a bang up job. I hope the pencils are living up to the inks.”
