The first barcode listed is printed on the back cover, the second on the otherwise blank inside front cover with the label "Direct Sales."
The title page illustration of Adam and Alanna is taken from the first panel of the fifth page of the first story in this volume. The verso is illustrated with an image of Adam Strange and Starbreaker.
The originally solicited cover to issue #4 featured silhouettes of Primus, Kalista (presumably), Harpis, Broot, Tigorr, and Nimbus (presumably). The printed cover removes Primus and Harpis, replaces Primus with Tigorr and Tigorr with Doc. However, Nimbus and Kalista do not appear in the story itself, and none of the other Omega Men who do match the silhouettes.
Inside front and back covers are blank (with the exception of the Direct Sales bardcode on the inside front cover).
