Rejuvenating radioactive chocolate

And now in the framework of radioactive incidents - about useful sweet. And it was for real - this is not Chernobyl vodka. Chocolate with radium was produced by the German company brown & Burke from 1931 to 1936. Yes, they did add radium and received five confirmations of medical centers and universities and two awards at international exhibitions. For truthfulness and concern for the sweet tooth. And it was sold under an advertising campaign about the rejuvenating effect. The funny thing is that as part of this campaign, it was proposed to send reviews to the editorial offices of two Newspapers about how you are getting younger and for the most beautiful letter you were given a package of radioactive chocolate. There were hundreds of reviews. Even with photos. In General, apparently, autosuggestion is a great thing.
