TwoMorrows Publishing has announced that it will release the T.H.U.N.D.E.R. Agents Companion in May, in conjunction with the 40th anniversary of the property.  The 192-page 8' x 11' trade paperback will include interviews with members of the original and subsequent creative teams, an examination of the history of the property (which has had numerous revivals since its initial run in the 60s), a rare 28-page story by Paul Gulacy, and previously unpublished stories by Gulacy, Paris Cullins, and others, all behind a Jerry Ordway cover.
