>I’ve been trying to locate a 1935 article supposedly published by the Indianapolis Times by Richard Helms titled “Hitler and Mars Incorporated.” I’ve tried the archives of the newspaper, Library of Congress, university archives, everything and can not locate a single copy.
Contact the LOC directly. Their online "Ask a Librarian" form may still be active, despite the shutdown. If not, wait and call them once open.
