File:FDA History - Hoxsey Fraud Warning Poster (4899254828).jpg

Photograph of the U.S. Food and Drug Administration's 1957 Public Beware! warning flyer against the Hoxsey cancer treatment, published to the FDA's own official Flickr account (fdaphotos, https://www.flickr.com/photos/fdaphotos/4899254828/) on 16 August 2010. Rights confirmed directly via the Wikimedia Commons file page: public domain as a U.S. government work, with FlickreviewR 2 confirming the license on 27 January 2018. The poster's own printed text, read directly from the image (not machine-fetched, so not covered by a verify-quotes block), states the treatment was found worthless by two Federal courts, that it costs $400 plus $60 in additional fees, and that not a single verified cure of internal cancer by the treatment had been found; it is issued under authority of 21 U.S.C. 375 and printed by the U.S. Government Printing Office in 1957 (order number O-411784, both printed on the flyer itself). A near-duplicate second Commons scan of the same 1957 flyer, file Warning Poster (FDA052) (7039697049).jpg, was downloaded during sourcing but dropped as editorially redundant rather than kept to pad the media floor.
