Writer revision from Eisner to French by Craig Delich.
Will Eisner created the Espionage feature, and Will Erwin was a pen name used by Will Eisner (Erwin was Eisner's middle name), but it also became a house by-line after Eisner's tenure after 1940. Lane French wrote the feature in 1941, followed by Toni Blum (1942) and Otto Binder (1942-43).
