Thanks to our good friend Arthur Moses, I get to share the Portuguese version of an article titled, How Does Houdini Do It? By William Eastman. The English version of this article first appeared in the May 1921 Physical Culture Magazine. The photos are the highlight of the article.
Bonus:
Below is a snippet from the May 1921 Physical Culture Magazine article that covers his movies.
That’s not a German article. Perhaps Portuguese?
I was told it was German, but your right, it looks like its Portuguese. Good catch Bill! I have updated the post. Thanks!
