I'm looking for the cover of a comic described in Cord A. Scott's Comics and conflict: patriotism and propaganda from WWII through Operation Iraqi Freedom. On page 15 of his book he writes the following:
"A particularly popular plot device was brainwashing, an example of which appeared in the story 'Grease Monkey Griffin' in Wings #15. This issue exhibits one of the most confusing adaptations of racial ideology imaginable. On the cover, a Zulu-like African warrior stands in the cockpit of a flying plane and throws a spear at an Allied plane—while carrying a copy of Mein Kampf in his other hand. In the story line, it is revealed that the tribesmen have been brainwashed by Nazis agents in the heart of the African jungle."
