Last week, we asked in our trivia question which breakfast cereal lent its name to a postal forgery operation. William Harnish correctly guess cornflakes and pointed to a Wikipedia article about the operation.
I thought of the question because of a publication that we just cataloged called The Story of Cornflakes, Pig Iron and Sheet Iron. The report was published in Rome in May 1945 and contains a written report as well as photos.
You can also read more about the operation in an article in the August 1984 American Philatelist, “‘Cornflakes’: Using Postal Forgeries to Place Anti-Nazi Literature on German Breakfast Tables.”
