This is the dust jacket cover for this collection, which has different artwork, than the actual hardcover front cover, shown in the next sequence.
This is the actual hardcover front cover, a blown-up section of the variant cover for The Kamandi Challenge (DC, 2017 Series) #4 (June 2017). The background is different than that of the original.
Story continues in the next story in this issue.
Mr. Royer and Mr. Kirby are in homage to Mike Royer and Jack Kirby who worked on the original Kamandi stories.
Dan Abnett explains how he would have gotten Kamandi out of the cliffhanger he wrote last issue.
