Justice League Of America Vol. 1 #031

Hawkman's first case as a member of the JLA involves low-level crook Joe Parry who has come into possession of an alien machine. A trio of bank robbers, wearing golden hoops, rob the Shore City bank. Security Guards, attempting to subdue the robbers, find the bullets from their guns disappear, before finding their mark. The Justice League of America arrive at the scene of the crime. They, too, are quick to discover that all of their attacks fade away before they can strike the robbers. Prior to the events of the robbery, the Atom made contact with Hawkman and Hawkgirl, in Midway City, to offer Hawkman membership in the Justice League of America. The Atom led Hawkman to the Secret Sanctuary, where Hawkaman was officially inducted into the ranks of the Justice League of America. After Aquaman, the Atom, the Green Arrow, J'onn J'onzz, the Martian Manhunter, and Superman departed to pursue individual cases, the call came in, regarding the robbery. The bank robbers make good their escape.
