Look through France Edward Herron's credited work at DC on Blackhawk and Challengers and you'll find "Kwhamma" a lot.
Otto Binder's attributions for the back-up pieces in the Thrillers line seem to have morphed into credits for the main features, but I can't find him on Spyman, for one. I can't even find his style on the Eye Spy backup in #1.
Nick Caputo gives Mike Esposito as a possibility for the inks for the first part of Tuska's story. A CGD guess at the second part's inks is Carl Pfeufer.
I suspect the intro pages on the Thrillers are more likely written by editor Joe Simon than by the main-feature writers.
