Reprints
During the craze for hero pulp reprints in the 1970s started by the success of Doc Savage reprints, Berkley Books reprinted 8 G-8 novels. The first 3 had covers by Jim Steranko and a logo inspired by Doc Savage's. After that, the covers reprinted the original pulp covers.
In more recent years, some G-8 novels were reprinted by small presses like Adventure House. Adventure House recently started a reprint series of G-8 in similar size to the original pulps, including covers and interior artwork. So far, they have reprinted over 40 issues.
