Though the 1949 example is cute, the use of “considered harmful” in the headline of a major newspaper is pretty rare. My search on the historical New York Times, Wall Street Journal, Chicago Defender, Los Angeles Times, and Washington Post (via ProQuest Historical Newspapers) turns a mere EIGHT headlines with the words “considered harmful” in them from the 19th through the 20th centuries.
Of those, only the 1949 is a pure case of “X considered harmful” without anything else. Here are the headlines:
