Here are the front and back covers to the NOMAN volume of the Tower paperback series that collected T.H.U.N.D.E.R. AGENTS stories in the mid-sixties. Note that whoever laid out the cover had no idea that the background villain was NOT just another drawing of NoMan himself! Thus the word balloon. The back cover is by Woody with, I'm pretty sure, Dan Adkins. The front MAY be by Reed Crandall with or without Wood and both seem at least a bit retouched by other hands. Interior art also includes work from Mike Sekowsky and Gil Kane.
